Description:

[0001] The present application claims the benefits of and priority, under
35 U.S.C. § 119(e), to U.S. Provisional Application Ser. No.
61/539,884, filed Sep. 27, 2011, entitled "MOBILE DEVICE," which is
incorporated herein by reference in its entirety for all that it teaches
and for all purposes.

BACKGROUND

[0002] A substantial number of handheld computing devices, such as
cellular phones, tablets, and E-Readers, make use of a touch screen
display not only to deliver display information to the user but also to
receive inputs from user interface commands. While touch screen displays
may increase the configurability of the handheld device and provide a
wide variety of user interface options, this flexibility typically comes
at a price. The dual use of the touch screen to provide content and
receive user commands, while flexible for the user, may obfuscate the
display and cause visual clutter, thereby leading to user frustration and
loss of productivity.

[0003] The small form factor of handheld computing devices requires a
careful balancing between the displayed graphics and the area provided
for receiving inputs. On the one hand, the small display constrains the
display space, which may increase the difficulty of interpreting actions
or results. On the other, a virtual keypad or other user interface scheme
is superimposed on or positioned adjacent to an executing application,
requiring the application to be squeezed into an even smaller portion of
the display.

[0004] This balancing act is particularly difficult for single display
touch screen devices. Single display touch screen devices are crippled by
their limited screen space. When users are entering information into the
device, through the single display, the ability to interpret information
in the display can be severely hampered, particularly when a complex
interaction between display and interface is required.

SUMMARY

[0005] There is a need for a dual multi-display handheld computing device
that provides for enhanced power and/or versatility compared to
conventional single display handheld computing devices. These and other
needs are addressed by the various aspects, embodiments, and/or
configurations of the present disclosure. Also, while the disclosure is
presented in terms of exemplary embodiments, it should be appreciated
that individual aspects of the disclosure can be separately claimed.

[0006] Additionally, it is desirable to have the multi-display device that
can use either display when the device is closed. Thus, the user, based
on the user's desires, can take better advantage of the phones
capabilities. The device can have at least two screens that face in
opposite directions when closed. A primary screen may be used for most
applications. However, the user, or by some other input or event, can
change the display to a secondary screen. Thus, the display may be
provided on the opposite screen facing the opposite direction.

[0007] The device described herein can include at least first and second
screens. In some circumstances, the device can receive user interface
input to execute a gallery function. The gallery function can adapt to
different device configurations to provide a user interface where a user
can view, manage, select different pictures or videos.

[0008] The phrases "at least one", "one or more", and "and/or" are
open-ended expressions that are both conjunctive and disjunctive in
operation. For example, each of the expressions "at least one of A, B and
C", "at least one of A, B, or C", "one or more of A, B, and C", "one or
more of A, B, or C" and "A, B, and/or C" means A alone, B alone, C alone,
A and B together, A and C together, B and C together, or A, B and C
together.

[0009] The term "a" or "an" entity refers to one or more of that entity.
As such, the terms "a" (or "an"), "one or more" and "at least one" can be
used interchangeably herein. It is also to be noted that the terms
"comprising", "including", and "having" can be used interchangeably.

[0010] The term "automatic" and variations thereof, as used herein, refers
to any process or operation done without material human input when the
process or operation is performed. However, a process or operation can be
automatic, even though performance of the process or operation uses
material or immaterial human input, if the input is received before
performance of the process or operation. Human input is deemed to be
material if such input influences how the process or operation will be
performed. Human input that consents to the performance of the process or
operation is not deemed to be "material".

[0011] The term "computer-readable medium" as used herein refers to any
tangible storage and/or transmission medium that participate in providing
instructions to a processor for execution. Such a medium may take many
forms, including but not limited to, non-volatile media, volatile media,
and transmission media. Non-volatile media includes, for example, NVRAM,
or magnetic or optical disks. Volatile media includes dynamic memory,
such as main memory. Common forms of computer-readable media include, for
example, a floppy disk, a flexible disk, hard disk, magnetic tape, or any
other magnetic medium, magneto-optical medium, a CD-ROM, any other
optical medium, punch cards, paper tape, any other physical medium with
patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, a solid state
medium like a memory card, any other memory chip or cartridge, a carrier
wave as described hereinafter, or any other medium from which a computer
can read. A digital file attachment to e-mail or other self-contained
information archive or set of archives is considered a distribution
medium equivalent to a tangible storage medium. When the
computer-readable media is configured as a database, it is to be
understood that the database may be any type of database, such as
relational, hierarchical, object-oriented, and/or the like. Accordingly,
the disclosure is considered to include a tangible storage medium or
distribution medium and prior art-recognized equivalents and successor
media, in which the software implementations of the present disclosure
are stored.

[0012] The term "desktop" refers to a metaphor used to portray systems. A
desktop is generally considered a "surface" that typically includes
pictures, called icons, widgets, folders, etc. that can activate show
applications, windows, cabinets, files, folders, documents, and other
graphical items. The icons are generally selectable to initiate a task
through user interface interaction to allow a user to execute
applications or conduct other operations.

[0013] The term "screen," "touch screen," or "touchscreen" refers to a
physical structure that includes one or more hardware components that
provide the device with the ability to render a user interface and/or
receive user input. A screen can encompass any combination of gesture
capture region, a touch sensitive display, and/or a configurable area.
The device can have one or more physical screens embedded in the
hardware. However a screen may also include an external peripheral device
that may be attached and detached from the device. In embodiments,
multiple external devices may be attached to the device. Thus, in
embodiments, the screen can enable the user to interact with the device
by touching areas on the screen and provides information to a user
through a display. The touch screen may sense user contact in a number of
different ways, such as by a change in an electrical parameter (e.g.,
resistance or capacitance), acoustic wave variations, infrared radiation
proximity detection, light variation detection, and the like. In a
resistive touch screen, for example, normally separated conductive and
resistive metallic layers in the screen pass an electrical current. When
a user touches the screen, the two layers make contact in the contacted
location, whereby a change in electrical field is noted and the
coordinates of the contacted location calculated. In a capacitive touch
screen, a capacitive layer stores electrical charge, which is discharged
to the user upon contact with the touch screen, causing a decrease in the
charge of the capacitive layer. The decrease is measured, and the
contacted location coordinates determined. In a surface acoustic wave
touch screen, an acoustic wave is transmitted through the screen, and the
acoustic wave is disturbed by user contact. A receiving transducer
detects the user contact instance and determines the contacted location
coordinates.

[0014] The term "display" refers to a portion of one or more screens used
to display the output of a computer to a user. A display may be a
single-screen display or a multi-screen display, referred to as a
composite display. A composite display can encompass the touch sensitive
display of one or more screens. A single physical screen can include
multiple displays that are managed as separate logical displays. Thus,
different content can be displayed on the separate displays although part
of the same physical screen.

[0015] The term "displayed image" refers to an image produced on the
display. A typical displayed image is a window or desktop. The displayed
image may occupy all or a portion of the display.

[0016] The term "display orientation" refers to the way in which a
rectangular display is oriented by a user for viewing. The two most
common types of display orientation are portrait and landscape. In
landscape mode, the display is oriented such that the width of the
display is greater than the height of the display (such as a 4:3 ratio,
which is 4 units wide and 3 units tall, or a 16:9 ratio, which is 16
units wide and 9 units tall). Stated differently, the longer dimension of
the display is oriented substantially horizontal in landscape mode while
the shorter dimension of the display is oriented substantially vertical.
In the portrait mode, by contrast, the display is oriented such that the
width of the display is less than the height of the display. Stated
differently, the shorter dimension of the display is oriented
substantially horizontal in the portrait mode while the longer dimension
of the display is oriented substantially vertical.

[0017] The term "composite display" refers to a logical structure that
defines a display that can encompass one or more screens. A multi-screen
display can be associated with a composite display that encompasses all
the screens. The composite display can have different display
characteristics based on the various orientations of the device.

[0018] The term "gesture" refers to a user action that expresses an
intended idea, action, meaning, result, and/or outcome. The user action
can include manipulating a device (e.g., opening or closing a device,
changing a device orientation, moving a trackball or wheel, etc.),
movement of a body part in relation to the device, movement of an
implement or tool in relation to the device, audio inputs, etc. A gesture
may be made on a device (such as on the screen) or with the device to
interact with the device.

[0019] The term "module" as used herein refers to any known or later
developed hardware, software, firmware, artificial intelligence, fuzzy
logic, or combination of hardware and software that is capable of
performing the functionality associated with that element.

[0020] The term "gesture capture" refers to a sense or otherwise a
detection of an instance and/or type of user gesture. The gesture capture
can occur in one or more areas of the screen, A gesture region can be on
the display, where it may be referred to as a touch sensitive display or
off the display where it may be referred to as a gesture capture area.

[0021] A "multi-screen application" or "multiple-display application"
refers to an application that is capable of multiple modes. The
multi-screen application mode can include, but is not limited to, a
single screen mode (where the application is displayed on a single
screen) or a composite display mode (where the application is displayed
on two or more screens). A multi-screen application can have different
layouts optimized for the mode. Thus, the multi-screen application can
have different layouts for a single screen or for a composite display
that can encompass two or more screens. The different layouts may have
different screen/display dimensions and/or configurations on which the
user interfaces of the multi-screen applications can be rendered. The
different layouts allow the application to optimize the application's
user interface for the type of display, e.g., single screen or multiple
screens. In single screen mode, the multi-screen application may present
one window pane of information. In a composite display mode, the
multi-screen application may present multiple window panes of information
or may provide a larger and a richer presentation because there is more
space for the display contents. The multi-screen applications may be
designed to adapt dynamically to changes in the device and the mode
depending on which display (single or composite) the system assigns to
the multi-screen application. In alternative embodiments, the user can
use a gesture to request the application transition to a different mode,
and, if a display is available for the requested mode, the device can
allow the application to move to that display and transition modes.

[0022] A "single-screen application" refers to an application that is
capable of single screen mode. Thus, the single-screen application can
produce only one window and may not be capable of different modes or
different display dimensions. A single-screen application may not be
capable of the several modes discussed with the multi-screen application.

[0023] The term "window" refers to a, typically rectangular, displayed
image on at least part of a display that contains or provides content
different from the rest of the screen. The window may obscure the
desktop.

[0024] The terms "determine", "calculate" and "compute," and variations
thereof, as used herein, are used interchangeably and include any type of
methodology, process, mathematical operation or technique.

[0025] It shall be understood that the term "means" as used herein shall
be given its broadest possible interpretation in accordance with 35
U.S.C., Section 112, Paragraph 6. Accordingly, a claim incorporating the
term "means" shall cover all structures, materials, or acts set forth
herein, and all of the equivalents thereof. Further, the structures,
materials or acts and the equivalents thereof shall include all those
described in the summary of the invention, brief description of the
drawings, detailed description, abstract, and claims themselves.

[0026] The preceding is a simplified summary of the disclosure to provide
an understanding of some aspects of the disclosure. This summary is
neither an extensive nor exhaustive overview of the disclosure and its
various aspects, embodiments, and/or configurations. It is intended
neither to identify key or critical elements of the disclosure nor to

DETAILED DESCRIPTION

[0107] Presented herein are embodiments of a device. The device can be a
communications device, such as a cellular telephone, or other smart
device. The device can include two screens that are oriented to provide
several unique display configurations. Further, the device can receive
user input in unique ways. The overall design and functionality of the
device provides for an enhanced user experience making the device more
useful and more efficient.

[0108] Mechanical Features:

[0109] FIGS. 1A-1J illustrate a device 100 in accordance with embodiments
of the present disclosure. As described in greater detail below, device
100 can be positioned in a number of different ways each of which
provides different functionality to a user. The device 100 is a
multi-screen device that includes a primary screen 104 and a secondary
screen 108, both of which are touch sensitive. In embodiments, the entire
front surface of screens 104 and 108 may be touch sensitive and capable
of receiving input by a user touching the front surface of the screens
104 and 108. Primary screen 104 includes touch sensitive display 110,
which, in addition to being touch sensitive, also displays information to
a user. Secondary screen 108 includes touch sensitive display 114, which
also displays information to a user. In other embodiments, screens 104
and 108 may include more than one display area.

[0110] Primary screen 104 also includes a configurable area 112 that has
been configured for specific inputs when the user touches portions of the
configurable area 112. Secondary screen 108 also includes a configurable
area 116 that has been configured for specific inputs. Areas 112a and
116a have been configured to receive a "back" input indicating that a
user would like to view information previously displayed. Areas 112b and
116b have been configured to receive a "menu" input indicating that the
user would like to view options from a menu. Areas 112c and 116c have
been configured to receive a "home" input indicating that the user would
like to view information associated with a "home" view. In other
embodiments, areas 112a-c and 116a-c may be configured, in addition to
the configurations described above, for other types of specific inputs
including controlling features of device 100, some non-limiting examples
including adjusting overall system power, adjusting the volume, adjusting
the brightness, adjusting the vibration, selecting of displayed items (on
either of screen 104 or 108), operating a camera, operating a microphone,
and initiating/terminating of telephone calls. Also, in some embodiments,
areas 112a-C and 116a-C may be configured for specific inputs depending
upon the application running on device 100 and/or information displayed
on touch sensitive displays 110 and/or 114.

[0111] In addition to touch sensing, primary screen 104 and secondary
screen 108 may also include areas that receive input from a user without
requiring the user to touch the display area of the screen. For example,
primary screen 104 includes gesture capture area 120, and secondary
screen 108 includes gesture capture area 124. These areas are able to
receive input by recognizing gestures made by a user without the need for
the user to actually touch the surface of the display area. In comparison
to touch sensitive displays 110 and 114, the gesture capture areas 120
and 124 are commonly not capable of rendering a displayed image.

[0112] The two screens 104 and 108 are connected together with a hinge
128, shown clearly in FIG. 1C (illustrating a back view of device 100).
Hinge 128, in the embodiment shown in FIGS. 1A-1J, is a center hinge that
connects screens 104 and 108 so that when the hinge is closed, screens
104 and 108 are juxtaposed (i.e., side-by-side) as shown in FIG. 1B
(illustrating a front view of device 100). Hinge 128 can be opened to
position the two screens 104 and 108 in different relative positions to
each other. As described in greater detail below, the device 100 may have
different functionalities depending on the relative positions of screens
104 and 108.

[0113] FIG. 1D illustrates the right side of device 100. As shown in FIG.
1D, secondary screen 108 also includes a card slot 132 and a port 136 on
its side. Card slot 132 in embodiments, accommodates different types of
cards including a subscriber identity module (SIM). Port 136 in
embodiments is an input/output port (I/O port) that allows device 100 to
be connected to other peripheral devices, such as a display, keyboard, or
printing device. As can be appreciated, these are merely some examples
and in other embodiments device 100 may include other slots and ports
such as slots and ports for accommodating additional memory devices
and/or for connecting other peripheral devices. Also shown in FIG. 1D is
an audio jack 140 that accommodates a tip, ring, sleeve (TRS) connector
for example to allow a user to utilize headphones or a headset.

[0114] Device 100 also includes a number of buttons 158. For example, FIG.
1E illustrates the left side of device 100. As shown in FIG. 1E, the side
of primary screen 104 includes three buttons 144, 148, and 152, which can
be configured for specific inputs. For example, buttons 144, 148, and 152
may be configured to, in combination or alone, control a number of
aspects of device 100. Some non-limiting examples include overall system
power, volume, brightness, vibration, selection of displayed items (on
either of screen 104 or 108), a camera, a microphone, and
initiation/termination of telephone calls. In some embodiments, instead
of separate buttons two buttons may be combined into a rocker button.
This arrangement is useful in situations where the buttons are configured
to control features such as volume or brightness. In addition to buttons
144, 148, and 152, device 100 also includes a button 156, shown in FIG.
1F, which illustrates the top of device 100. In one embodiment, button
156 is configured as an on/off button used to control overall system
power to device 100. In other embodiments, button 156 is configured to,
in addition to or in lieu of controlling system power, control other
aspects of device 100. In some embodiments, one or more of the buttons
144, 148, 152, and 156 are capable of supporting different user commands.
By way of example, a normal press has a duration commonly of less than
about 1 second and resembles a quick tap. A medium press has a duration
commonly of 1 second or more but less than about 12 seconds. A long press
has a duration commonly of about 12 seconds or more. The function of the
buttons is normally specific to the application that is currently in
focus on the respective display 110 and 114. In a telephone application
for instance and depending on the particular button, a normal, medium, or
long press can mean end call, increase in call volume, decrease in call
volume, and toggle microphone mute. In a camera or video application for
instance and depending on the particular button, a normal, medium, or
long press can mean increase zoom, decrease zoom, and take photograph or
record video.

[0115] There are also a number of hardware components within device 100.
As illustrated in FIG. 1C, device 100 includes a speaker 160 and a
microphone 164. Device 100 also includes a camera 168 (FIG. 1B).
Additionally, device 100 includes two position sensors 172A and 172B,
which are used to determine the relative positions of screens 104 and
108. In one embodiment, position sensors 172A and 172B are Hall effect
sensors. However, in other embodiments other sensors can be used in
addition to or in lieu of the Hall effect sensors. An accelerometer 176
may also be included as part of device 100 to determine the orientation
of the device 100 and/or the orientation of screens 104 and 108.
Additional internal hardware components that may be included in device
100 are described below with respect to FIG. 2.

[0116] The overall design of device 100 allows it to provide additional
functionality not available in other communication devices. Some of the
functionality is based on the various positions and orientations that
device 100 can have. As shown in FIGS. 1B-1G, device 100 can be operated
in an "open" position where screens 104 and 108 are juxtaposed. This
position allows a large display area for displaying information to a
user. When position sensors 172A and 172B determine that device 100 is in
the open position, they can generate a signal that can be used to trigger
different events such as displaying information on both screens 104 and
108. Additional events may be triggered if accelerometer 176 determines
that device 100 is in a portrait position (FIG. 1B) as opposed to a
landscape position (not shown).

[0117] In addition to the open position, device 100 may also have a
"closed" position illustrated in FIG. 1H. Again, position sensors 172A
and 172B can generate a signal indicating that device 100 is in the
"closed" position. This can trigger an event that results in a change of
displayed information on screen 104 and/or 108. For example, device 100
may be programmed to stop displaying information on one of the screens,
e.g., screen 108, since a user can only view one screen at a time when
device 100 is in the "closed" position. In other embodiments, the signal
generated by position sensors 172A and 172B, indicating that the device
100 is in the "closed" position, can trigger device 100 to answer an
incoming telephone call. The "closed" position can also be a preferred
position for utilizing the device 100 as a mobile phone.

[0118] Device 100 can also be used in an "easel" position which is
illustrated in FIG. 11. In the "easel" position, screens 104 and 108 are
angled with respect to each other and facing outward with the edges of
screens 104 and 108 substantially horizontal. In this position, device
100 can be configured to display information on both screens 104 and 108
to allow two users to simultaneously interact with device 100. When
device 100 is in the "easel" position, sensors 172A and 172B generate a
signal indicating that the screens 104 and 108 are positioned at an angle
to each other, and the accelerometer 176 can generate a signal indicating
that device 100 has been placed so that the edge of screens 104 and 108
are substantially horizontal. The signals can then be used in combination
to generate events that trigger changes in the display of information on
screens 104 and 108.

[0119] FIG. 1J illustrates device 100 in a "modified easel" position. In
the "modified easel" position, one of screens 104 or 108 is used as a
stand and is faced down on the surface of an object such as a table. This
position provides a convenient way for information to be displayed to a
user in landscape orientation. Similar to the easel position, when device
100 is in the "modified easel" position, position sensors 172A and 172B
generate a signal indicating that the screens 104 and 108 are positioned
at an angle to each other. The accelerometer 176 would generate a signal
indicating that device 100 has been positioned so that one of screens 104
and 108 is faced downwardly and is substantially horizontal. The signals
can then be used to generate events that trigger changes in the display
of information of screens 104 and 108. For example, information may not
be displayed on the screen that is face down since a user cannot see the
screen.

[0120] Transitional states are also possible. When the position sensors
172A and B and/or accelerometer indicate that the screens are being
closed or folded (from open), a closing transitional state is recognized.
Conversely when the position sensors 172A and B indicate that the screens
are being opened or folded (from closed), an opening transitional state
is recognized. The closing and opening transitional states are typically
time-based, or have a maximum time duration from a sensed starting point.
Normally, no user input is possible when one of the closing and opening
states is in effect. In this manner, incidental user contact with a
screen during the closing or opening function is not misinterpreted as
user input. In embodiments, another transitional state is possible when
the device 100 is closed. This additional transitional state allows the
display to switch from one screen 104 to the second screen 108 when the
device 100 is closed based on some user input, e.g., a double tap on the
screen 110,114.

[0121] As can be appreciated, the description of device 100 is made for
illustrative purposes only, and the embodiments are not limited to the
specific mechanical features shown in FIGS. 1A-1J and described above. In
other embodiments, device 100 may include additional features, including
one or more additional buttons, slots, display areas, hinges, and/or
locking mechanisms. Additionally, in embodiments, the features described
above may be located in different parts of device 100 and still provide
similar functionality. Therefore, FIGS. 1A-1J and the description
provided above are nonlimiting.

[0122] Hardware Features:

[0123]FIG. 2 illustrates components of a device 100 in accordance with
embodiments of the present disclosure. In general, the device 100
includes a primary screen 104 and a secondary screen 108. While the
primary screen 104 and its components are normally enabled in both the
opened and closed positions or states, the secondary screen 108 and its
components are normally enabled in the opened state but disabled in the
closed state. However, even when in the closed state a user or
application triggered interrupt (such as in response to a phone
application or camera application operation) can flip the active screen,
or disable the primary screen 104 and enable the secondary screen 108, by
a suitable command. Each screen 104, 108 can be touch sensitive and can
include different operative areas. For example, a first operative area,
within each touch sensitive screen 104 and 108, may comprise a touch
sensitive display 110, 114. In general, the touch sensitive display 110,
114 may comprise a full color, touch sensitive display. A second area
within each touch sensitive screen 104 and 108 may comprise a gesture
capture region 120, 124. The gesture capture region 120, 124 may comprise
an area or region that is outside of the touch sensitive display 110, 114
area, and that is capable of receiving input, for example in the form of
gestures provided by a user. However, the gesture capture region 120, 124
does not include pixels that can perform a display function or
capability.

[0124] A third region of the touch sensitive screens 104 and 108 may
comprise a configurable area 112, 116. The configurable area 112, 116 is
capable of receiving input and has display or limited display
capabilities. In embodiments, the configurable area 112, 116 may present
different input options to the user. For example, the configurable area
112, 116 may display buttons or other relatable items. Moreover, the
identity of displayed buttons, or whether any buttons are displayed at
all within the configurable area 112, 116 of a touch sensitive screen 104
or 108, may be determined from the context in which the device 100 is
used and/or operated. In an exemplary embodiment, the touch sensitive
screens 104 and 108 comprise liquid crystal display devices extending
across at least those regions of the touch sensitive screens 104 and 108
that are capable of providing visual output to a user, and a capacitive
input matrix over those regions of the touch sensitive screens 104 and
108 that are capable of receiving input from the user.

[0125] One or more display controllers 216a, 216b may be provided for
controlling the operation of the touch sensitive screens 104 and 108,
including input (touch sensing) and output (display) functions. In the
exemplary embodiment illustrated in FIG. 2, a separate touch screen
controller 216a or 216b is provided for each touch screen 104 and 108. In
accordance with alternate embodiments, a common or shared touch screen
controller 216 may be used to control each of the included touch
sensitive screens 104 and 108. In accordance with still other
embodiments, the functions of a touch screen controller 216 may be
incorporated into other components, such as a processor 204.

[0126] The processor 204 may comprise a general purpose programmable
processor or controller for executing application programming or
instructions. In accordance with at least some embodiments, the processor
204 may include multiple processor cores, and/or implement multiple
virtual processors. In accordance with still other embodiments, the
processor 204 may include multiple physical processors. As a particular
example, the processor 204 may comprise a specially configured
application specific integrated circuit (ASIC) or other integrated
circuit, a digital signal processor, a controller, a hardwired electronic
or logic circuit, a programmable logic device or gate array, a special
purpose computer, or the like. The processor 204 generally functions to
run programming code or instructions implementing various functions of
the device 100.

[0127] A communication device 100 may also include memory 208 for use in
connection with the execution of application programming or instructions
by the processor 204, and for the temporary or long term storage of
program instructions and/or data. As examples, the memory 208 may
comprise RAM, DRAM, SDRAM, or other solid state memory. Alternatively or
in addition, data storage 212 may be provided. Like the memory 208, the
data storage 212 may comprise a solid state memory device or devices.
Alternatively or in addition, the data storage 212 may comprise a hard
disk drive or other random access memory.

[0128] In support of communications functions or capabilities, the device
100 can include a cellular telephony module 228. As examples, the
cellular telephony module 228 can comprise a GSM, CDMA, FDMA and/or
analog cellular telephony transceiver capable of supporting voice,
multimedia and/or data transfers over a cellular network. Alternatively
or in addition, the device 100 can include an additional or other
wireless communications module 232. As examples, the other wireless
communications module 232 can comprise a Wi-Fi, BLUETOOTH TM, WiMax,
infrared, or other wireless communications link. The cellular telephony
module 228 and the other wireless communications module 232 can each be
associated with a shared or a dedicated antenna 224.

[0129] A port interface 252 may be included. The port interface 252 may
include proprietary or universal ports to support the interconnection of
the device 100 to other devices or components, such as a dock, which may
or may not include additional or different capabilities from those
integral to the device 100. In addition to supporting an exchange of
communication signals between the device 100 and another device or
component, the docking port 136 and/or port interface 252 can support the
supply of power to or from the device 100. The port interface 252 also
comprises an intelligent element that comprises a docking module for
controlling communications or other interactions between the device 100
and a connected device or component.

[0130] An input/output module 248 and associated ports may be included to
support communications over wired networks or links, for example with
other communication devices, server devices, and/or peripheral devices.
Examples of an input/output module 248 include an Ethernet port, a
Universal Serial Bus (USB) port, Institute of Electrical and Electronics
Engineers (IEEE) 1394, or other interface.

[0131] An audio input/output interface/device(s) 244 can be included to
provide analog audio to an interconnected speaker or other device, and to
receive analog audio input from a connected microphone or other device.
As an example, the audio input/output interface/device(s) 244 may
comprise an associated amplifier and analog to digital converter.
Alternatively or in addition, the device 100 can include an integrated
audio input/output device 256 and/or an audio jack for interconnecting an
external speaker or microphone. For example, an integrated speaker and an
integrated microphone can be provided, to support near talk or speaker
phone operations.

[0132] Hardware buttons 158 can be included for example for use in
connection with certain control operations. Examples include a master
power switch, volume control, etc., as described in conjunction with
FIGS. 1A through 1J. One or more image capture interfaces/devices 240,
such as a camera, can be included for capturing still and/or video
images. Alternatively or in addition, an image capture interface/device
240 can include a scanner or code reader. An image capture
interface/device 240 can include or be associated with additional
elements, such as a flash or other light source.

[0133] The device 100 can also include a global positioning system (GPS)
receiver 236. In accordance with embodiments of the present invention,
the GPS receiver 236 may further comprise a GPS module that is capable of
providing absolute location information to other components of the device
100. An accelerometer(s) 176 may also be included. For example, in
connection with the display of information to a user and/or other
functions, a signal from the accelerometer 176 can be used to determine
an orientation and/or format in which to display that information to the
user.

[0134] Embodiments of the present invention can also include one or more
position sensor(s) 172. The position sensor 172 can provide a signal
indicating the position of the touch sensitive screens 104 and 108
relative to one another. This information can be provided as an input,
for example to a user interface application, to determine an operating
mode, characteristics of the touch sensitive displays 110, 114, and/or
other device 100 operations. As examples, a screen position sensor 172
can comprise a series of Hall effect sensors, a multiple position switch,
an optical switch, a Wheatstone bridge, a potentiometer, or other
arrangement capable of providing a signal indicating of multiple relative
positions the touch screens are in.

[0135] Communications between various components of the device 100 can be
carried by one or more buses 222. In addition, power can be supplied to
the components of the device 100 from a power source and/or power control
module 260. The power control module 260 can, for example, include a
battery, an AC to DC converter, power control logic, and/or ports for
interconnecting the device 100 to an external source of power.

[0136] Device State:

[0137] FIGS. 3A and 3B represent illustrative states of device 100. While
a number of illustrative states are shown, and transitions from a first
state to a second state, it is to be appreciated that the illustrative
state diagram may not encompass all possible states and/or all possible
transitions from a first state to a second state. As illustrated in FIG.
3, the various arrows between the states (illustrated by the state
represented in the circle) represent a physical change that occurs to the
device 100, that is detected by one or more of hardware and software, the
detection triggering one or more of a hardware and/or software interrupt
that is used to control and/or manage one or more functions of device
100.

[0138] As illustrated in FIG. 3A, there are twelve exemplary "physical"
states: closed 304, transition 308 (or opening transitional state), easel
312, modified easel 316, open 320, inbound/outbound call or communication
324, image/video capture 328, transition 332 (or closing transitional
state), landscape 340, docked 336, docked 344 and landscape 348. Next to
each illustrative state is a representation of the physical state of the
device 100 with the exception of states 324 and 328, where the state is
generally symbolized by the international icon for a telephone and the
icon for a camera, respectfully.

[0139] In state 304, the device is in a closed state with the device 100
generally oriented in the portrait direction with the primary screen 104
and the secondary screen 108 back-to-back in different planes (see FIG.
1H). From the closed state, the device 100 can enter, for example, docked
state 336, where the device 100 is coupled with a docking station,
docking cable, or in general docked or associated with one or more other
devices or peripherals, or the landscape state 340, where the device 100
is generally oriented with the primary screen 104 facing the user, and
the primary screen 104 and the secondary screen 108 being back-to-back.

[0140] In the closed state, the device can also move to a transitional
state where the device remains closed by the display is moved from one
screen 104 to another screen 108 based on a user input, e.g., a double
tap on the screen 110, 114. Still another embodiment includes a bilateral
state. In the bilateral state, the device remains closed, but a single
application displays at least one window on both the first display 110
and the second display 114. The windows shown on the first and second
display 110, 114 may be the same or different based on the application
and the state of that application. For example, while acquiring an image
with a camera, the device may display the view finder on the first
display 110 and displays a preview for the photo subjects (full screen
and mirrored left-to-right) on the second display 114.

[0141] In state 308, a transition state from the closed state 304 to the
semi-open state or easel state 312, the device 100 is shown opening with
the primary screen 104 and the secondary screen 108 being rotated around
a point of axis coincidence with the hinge. Upon entering the easel state
312, the primary screen 104 and the secondary screen 108 are separated
from one another such that, for example, the device 100 can sit in an
easel-like configuration on a surface.

[0142] In state 316, known as the modified easel position, the device 100
has the primary screen 104 and the secondary screen 108 in a similar
relative relationship to one another as in the easel state 312, with the
difference being one of the primary screen 104 or the secondary screen
108 are placed on a surface as shown.

[0143] State 320 is the open state where the primary screen 104 and the
secondary screen 108 are generally on the same plane. From the open
state, the device 100 can transition to the docked state 344 or the open
landscape state 348. In the open state 320, the primary screen 104 and
the secondary screen 108 are generally in the portrait-like orientation
while in landscaped state 348 the primary screen 104 and the secondary
screen 108 are generally in a landscape-like orientation.

[0144] State 324 is illustrative of a communication state, such as when an
inbound or outbound call is being received or placed, respectively, by
the device 100. While not illustrated for clarity, it should be
appreciated the device 100 can transition to the inbound/outbound call
state 324 from any state illustrated in FIG. 3. In a similar manner, the
image/video capture state 328 can be entered into from any other state in
FIG. 3, with the image/video capture state 328 allowing the device 100 to
take one or more images via a camera and/or videos with a video capture
device 240.

[0145] Transition state 322 illustratively shows primary screen 104 and
the secondary screen 108 being closed upon one another for entry into,
for example, the closed state 304.

[0146]FIG. 3B illustrates, with reference to the key, the inputs that are
received to detect a transition from a first state to a second state. In
FIG. 3B, various combinations of states are shown with in general, a
portion of the columns being directed toward a portrait state 352, a
landscape state 356, and a portion of the rows being directed to portrait
state 360 and landscape state 364.

[0147] In FIG. 3B, the Key indicates that "H" represents an input from one
or more Hall Effect sensors, "A" represents an input from one or more
accelerometers, "T" represents an input from a timer, "P" represents a
communications trigger input and "I" represents an image and/or video
capture request input. Thus, in the center portion 376 of the chart, an
input, or combination of inputs, are shown that represent how the device
100 detects a transition from a first physical state to a second physical
state.

[0148] As discussed, in the center portion of the chart 376, the inputs
that are received enable the detection of a transition from, for example,
a portrait open state to a landscape easel state--shown in bold--"HAT."
For this exemplary transition from the portrait open to the landscape
easel state, a Hall Effect sensor ("H"), an accelerometer ("A") and a
timer ("T") input may be needed. The timer input can be derived from, for
example, a clock associated with the processor.

[0149] In addition to the portrait and landscape states, a docked state
368 is also shown that is triggered based on the receipt of a docking
signal 372. As discussed above and in relation to FIG. 3, the docking
signal can be triggered by the association of the device 100 with one or
more other device 100s, accessories, peripherals, smart docks, or the
like.

[0150] User Interaction:

[0151] FIGS. 4A through 4H depict various graphical representations of
gesture inputs that may be recognized by the screens 104, 108. The
gestures may be performed not only by a user's body part, such as a
digit, but also by other devices, such as a stylus, that may be sensed by
the contact sensing portion(s) of a screen 104, 108. In general, gestures
are interpreted differently, based on where the gestures are performed
(either directly on the display 110, 114 or in the gesture capture region
120, 124). For example, gestures in the display 110,114 may be directed
to a desktop or application, and gestures in the gesture capture region
120, 124 may be interpreted as for the system.

[0152] With reference to FIGS. 4A-4H, a first type of gesture, a touch
gesture 420, is substantially stationary on the screen 104,108 for a
selected length of time. A circle 428 represents a touch or other contact
type received at particular location of a contact sensing portion of the
screen. The circle 428 may include a border 432, the thickness of which
indicates a length of time that the contact is held substantially
stationary at the contact location. For instance, a tap 420 (or short
press) has a thinner border 432a than the border 432b for a long press
424 (or for a normal press). The long press 424 may involve a contact
that remains substantially stationary on the screen for longer time
period than that of a tap 420. As will be appreciated, differently
defined gestures may be registered depending upon the length of time that
the touch remains stationary prior to contact cessation or movement on
the screen.

[0153] With reference to FIG. 4C, a drag gesture 400 on the screen 104,108
is an initial contact (represented by circle 428) with contact movement
436 in a selected direction. The initial contact 428 may remain
stationary on the screen 104,108 for a certain amount of time represented
by the border 432. The drag gesture typically requires the user to
contact an icon, window, or other displayed image at a first location
followed by movement of the contact in a drag direction to a new second
location desired for the selected displayed image. The contact movement
need not be in a straight line but have any path of movement so long as
the contact is substantially continuous from the first to the second
locations.

[0154] With reference to FIG. 4D, a flick gesture 404 on the screen
104,108 is an initial contact (represented by circle 428) with truncated
contact movement 436 (relative to a drag gesture) in a selected
direction. In embodiments, a flick has a higher exit velocity for the
last movement in the gesture compared to the drag gesture. The flick
gesture can, for instance, be a finger snap following initial contact.
Compared to a drag gesture, a flick gesture generally does not require
continual contact with the screen 104,108 from the first location of a
displayed image to a predetermined second location. The contacted
displayed image is moved by the flick gesture in the direction of the
flick gesture to the predetermined second location. Although both
gestures commonly can move a displayed image from a first location to a
second location, the temporal duration and distance of travel of the
contact on the screen is generally less for a flick than for a drag
gesture.

[0155] With reference to FIG. 4E, a pinch gesture 408 on the screen
104,108 is depicted. The pinch gesture 408 may be initiated by a first
contact 428a to the screen 104,108 by, for example, a first digit and a
second contact 428b to the screen 104,108 by, for example, a second
digit. The first and second contacts 428a,b may be detected by a common
contact sensing portion of a common screen 104,108, by different contact
sensing portions of a common screen 104 or108, or by different contact
sensing portions of different screens. The first contact 428a is held for
a first amount of time, as represented by the border 432a, and the second
contact 428b is held for a second amount of time, as represented by the
border 432b. The first and second amounts of time are generally
substantially the same, and the first and second contacts 428 a, b
generally occur substantially simultaneously. The first and second
contacts 428 a, b generally also include corresponding first and second
contact movements 436 a, b, respectively. The first and second contact
movements 436 a, b are generally in opposing directions. Stated another
way, the first contact movement 436a is towards the second contact 436b,
and the second contact movement 436b is towards the first contact 436a.
More simply stated, the pinch gesture 408 may be accomplished by a user's
digits touching the screen 104,108 in a pinching motion.

[0156] With reference to FIG. 4F, a spread gesture 410 on the screen
104,108 is depicted. The spread gesture 410 may be initiated by a first
contact 428a to the screen 104,108 by, for example, a first digit and a
second contact 428b to the screen 104,108 by, for example, a second
digit. The first and second contacts 428a,b may be detected by a common
contact sensing portion of a common screen 104,108, by different contact
sensing portions of a common screen 104,108, or by different contact
sensing portions of different screens. The first contact 428a is held for
a first amount of time, as represented by the border 432a, and the second
contact 428b is held for a second amount of time, as represented by the
border 432b. The first and second amounts of time are generally
substantially the same, and the first and second contacts 428 a, b
generally occur substantially simultaneously. The first and second
contacts 428 a, b generally also include corresponding first and second
contact movements 436a, b, respectively. The first and second contact
movements 436 a, b are generally in a common direction. Stated another
way, the first and second contact movements 436 a, b are away from the
first and second contacts 428a, b. More simply stated, the spread gesture
410 may be accomplished by a user's digits touching the screen 104,108 in
a spreading motion.

[0157] The above gestures may be combined in any manner, such as those
shown by FIGS. 4G and 4H, to produce a determined functional result. For
example, in FIG. 4G a tap gesture 420 is combined with a drag or flick
gesture 412 in a direction away from the tap gesture 420. In FIG. 4H, a
tap gesture 420 is combined with a drag or flick gesture 412 in a
direction towards the tap gesture 420.

[0158] The functional result of receiving a gesture can vary depending on
a number of factors, including a state of the device 100, display 110,
114, or screen 104, 108, a context associated with the gesture, or sensed
location of the gesture. The state of the device commonly refers to one
or more of a configuration of the device 100, a display orientation, and
user and other inputs received by the device 100. Context commonly refers
to one or more of the particular application(s) selected by the gesture
and the portion(s) of the application currently executing, whether the
application is a single- or multi-screen application, and whether the
application is a multi-screen application displaying one or more windows
in one or more screens or in one or more stacks. Sensed location of the
gesture commonly refers to whether the sensed set(s) of gesture location
coordinates are on a touch sensitive display 110, 114 or a gesture
capture region 120, 124, whether the sensed set(s) of gesture location
coordinates are associated with a common or different display or screen
104,108, and/or what portion of the gesture capture region contains the
sensed set(s) of gesture location coordinates.

[0159] A tap, when received by an a touch sensitive display 110, 114, can
be used, for instance, to select an icon to initiate or terminate
execution of a corresponding application, to maximize or minimize a
window, to reorder windows in a stack, and to provide user input such as
by keyboard display or other displayed image. A drag, when received by a
touch sensitive display 110, 114, can be used, for instance, to relocate
an icon or window to a desired location within a display, to reorder a
stack on a display, or to span both displays (such that the selected
window occupies a portion of each display simultaneously). A flick, when
received by a touch sensitive display 110, 114 or a gesture capture
region 120, 124, can be used to relocate a window from a first display to
a second display or to span both displays (such that the selected window
occupies a portion of each display simultaneously). Unlike the drag
gesture, however, the flick gesture is generally not used to move the
displayed image to a specific user-selected location but to a default
location that is not configurable by the user.

[0160] The pinch gesture, when received by a touch sensitive display 110,
114 or a gesture capture region 120, 124, can be used to minimize or
otherwise increase the displayed area or size of a window (typically when
received entirely by a common display), to switch windows displayed at
the top of the stack on each display to the top of the stack of the other
display (typically when received by different displays or screens), or to
display an application manager (a "pop-up window" that displays the
windows in the stack). The spread gesture, when received by a touch
sensitive display 110, 114 or a gesture capture region 120, 124, can be
used to maximize or otherwise decrease the displayed area or size of a
window, to switch windows displayed at the top of the stack on each
display to the top of the stack of the other display (typically when
received by different displays or screens), or to display an application
manager (typically when received by an off-screen gesture capture region
on the same or different screens).

[0161] The combined gestures of FIG. 4G, when received by a common display
capture region in a common display or screen 104,108, can be used to hold
a first window stack location in a first stack constant for a display
receiving the gesture while reordering a second window stack location in
a second window stack to include a window in the display receiving the
gesture. The combined gestures of FIG. 4H, when received by different
display capture regions in a common display or screen 104,108 or in
different displays or screens, can be used to hold a first window stack
location in a first window stack constant for a display receiving the tap
part of the gesture while reordering a second window stack location in a
second window stack to include a window in the display receiving the
flick or drag gesture. Although specific gestures and gesture capture
regions in the preceding examples have been associated with corresponding
sets of functional results, it is to be appreciated that these
associations can be redefined in any manner to produce differing
associations between gestures and/or gesture capture regions and/or
functional results.

[0162] Firmware and Software:

[0163] The memory 508 may store and the processor 504 may execute one or
more software components. These components can include at least one
operating system (OS) 516, an application manager 562, a desktop 566,
and/or one or more applications 564a and/or 564b from an application
store 560. The OS 516 can include a framework 520, one or more frame
buffers 548, one or more drivers 512, previously described in conjunction
with FIG. 2, and/or a kernel 518. The OS 516 can be any software,
consisting of programs and data, which manages computer hardware
resources and provides common services for the execution of various
applications 564. The OS 516 can be any operating system and, at least in
some embodiments, dedicated to mobile devices, including, but not limited
to, Linux, ANDROID TM, iPhone OS (IOS TM), WINDOWS PHONE 7 TM, etc. The
OS 516 is operable to provide functionality to the phone by executing one
or more operations, as described herein.

[0164] The applications 564 can be any higher level software that executes
particular functionality for the user. Applications 564 can include
programs such as email clients, web browsers, texting applications,
games, media players, office suites, etc. The applications 564 can be
stored in an application store 560, which may represent any memory or
data storage, and the management software associated therewith, for
storing the applications 564. Once executed, the applications 564 may be
run in a different area of memory 508.

[0165] The framework 520 may be any software or data that allows the
multiple tasks running on the device to interact. In embodiments, at
least portions of the framework 520 and the discrete components described
hereinafter may be considered part of the OS 516 or an application 564.
However, these portions will be described as part of the framework 520,
but those components are not so limited. The framework 520 can include,
but is not limited to, a Multi-Display Management (MDM) module 524, a
Surface Cache module 528, a Window Management module 532, an Input
Management module 536, a Task Management module 540, an Application Model
Manager 542, a Display Controller, one or more frame buffers 548, a task
stack 552, one or more window stacks 550 (which is a logical arrangement
of windows and/or desktops in a display area), and/or an event buffer
556.

[0166] The MDM module 524 includes one or more modules that are operable
to manage the display of applications or other data on the screens of the
device. An embodiment of the MDM module 524 is described in conjunction
with FIG. 5B. In embodiments, the MDM module 524 receives inputs from the
other OS 516 components, such as, the drivers 512, and from the
applications 564 to determine continually the state of the device 100.
The inputs assist the MDM module 524 in determining how to configure and
allocate the displays according to the application's preferences and
requirements, and the user's actions. Once a determination for display
configurations is made, the MDM module 524 can bind the applications 564
to a display. The configuration may then be provided to one or more other
components to generate a window with a display.

[0167] The Surface Cache module 528 includes any memory or storage and the
software associated therewith to store or cache one or more images of
windows. A series of active and/or non-active windows (or other display
objects, such as, a desktop display) can be associated with each display.
An active window (or other display object) is currently displayed. A
non-active windows (or other display objects) were opened and, at some
time, displayed but are now not displayed. To enhance the user
experience, before a window transitions from an active state to an
inactive state, a "screen shot" of a last generated image of the window
(or other display object) can be stored. The Surface Cache module 528 may
be operable to store a bitmap of the last active image of a window (or
other display object) not currently displayed. Thus, the Surface Cache
module 528 stores the images of non-active windows (or other display
objects) in a data store.

[0168] In embodiments, the Window Management module 532 is operable to
manage the windows (or other display objects) that are active or not
active on each of the displays. The Window Management module 532, based
on information from the MDM module 524, the OS 516, or other components,
determines when a window (or other display object) is visible or not
active. The Window Management module 532 may then put a non-visible
window (or other display object) in a "not active state" and, in
conjunction with the Task Management module Task Management 540 suspends
the application's operation. Further, the Window Management module 532
may assign, through collaborative interaction with the MDM module 524, a
display identifier to the window (or other display object) or manage one
or more other items of data associated with the window (or other display
object). The Window Management module 532 may also provide the stored
information to the application 564, the Task Management module 540, or
other components interacting with or associated with the window (or other
display object). The Window Management module 532 can also associate an
input task with a window based on window focus and display coordinates
within the motion space.

[0169] The Input Management module 536 is operable to manage events that
occur with the device. An event is any input into the window environment,
for example, a user interface interactions with a user. The Input
Management module 536 receives the events and logically stores the events
in an event buffer 556. Events can include such user interface
interactions as a "down event," which occurs when a screen 104, 108
receives a touch signal from a user, a "move event," which occurs when
the screen 104, 108 determines that a user's finger is moving across a
screen(s), an "up event, which occurs when the screen 104, 108 determines
that the user has stopped touching the screen 104, 108, etc. These events
are received, stored, and forwarded to other modules by the Input
Management module 536. The Input Management module 536 may also map
screen inputs to a motion space which is the culmination of all physical
and virtual display available on the device.

[0170] The motion space is a virtualized space that includes all touch
sensitive displays 110,114 "tiled" together to mimic the physical
dimensions of the device 100. For example, when the device 100 is
unfolded, the motion space size may be 960×800, which may be the
number of pixels in the combined display area for both touch sensitive
displays 110, 114. If a user touches on a first touch sensitive display
110 on location (40, 40), a full screen window can receive touch event
with location (40, 40). If a user touches on a second touch sensitive
display 114, with location (40, 40), the full screen window can receive
touch event with location (520, 40), because the second touch sensitive
display 114 is on the right side of the first touch sensitive display
110, so the device 100 can offset the touch by the first touch sensitive
display's 110 width, which is 480 pixels. When a hardware event occurs
with location info from a driver 512, the framework 520 can up-scale the
physical location to the motion space because the location of the event
may be different based on the device orientation and state. The motion
space may be as described in U.S. patent application Ser. No. 13/187,026,
filed Jul. 20, 2011, entitled "Systems and Methods for Receiving Gesture
Inputs Spanning Multiple Input Devices," which is hereby incorporated by
reference in its entirety for all that it teaches and for all purposes.

[0171] A task can be an application and a sub-task can be an application
component that provides a window with which users can interact to do
something, such as dial the phone, take a photo, send an email, or view a
map. Each task may be given a window in which to draw a user interface.
The window typically fills a display (for example, touch sensitive
display 110,114), but may be smaller than the display 110,114 and float
on top of other windows. An application usually consists of multiple
sub-tasks that are loosely bound to each other. Typically, one task in an
application is specified as the "main" task, which is presented to the
user when launching the application for the first time. Each task can
then start another task or sub-task to perform different actions.

[0172] The Task Management module 540 is operable to manage the operation
of one or more applications 564 that may be executed by the device. Thus,
the Task Management module 540 can receive signals to launch, suspend,
terminate, etc. an application or application sub-tasks stored in the
application store 560. The Task Management module 540 may then
instantiate one or more tasks or sub-tasks of the application 564 to
begin operation of the application 564. Further, the Task Management
Module 540 may launch, suspend, or terminate a task or sub-task as a
result of user input or as a result of a signal from a collaborating
framework 520 component. The Task Management Module 540 is responsible
for managing the lifecycle of applications (tasks and sub-task) from when
the application is launched to when the application is terminated.

[0173] The processing of the Task Management Module 540 is facilitated by
a task stack 552, which is a logical structure associated with the Task
Management Module 540. The task stack 552 maintains the state of all
tasks and sub-tasks on the device 100. When some component of the
operating system 516 requires a task or sub-task to transition in its
lifecycle, the OS 516 component can notify the Task Management Module
540. The Task Management Module 540 may then locate the task or sub-task,
using identification information, in the task stack 552, and send a
signal to the task or sub-task indicating what kind of lifecycle
transition the task needs to execute. Informing the task or sub-task of
the transition allows the task or sub-task to prepare for the lifecycle
state transition. The Task Management Module 540 can then execute the
state transition for the task or sub-task. In embodiments, the state
transition may entail triggering the OS kernel 518 to terminate the task
when termination is required.

[0174] Further, the Task Management module 540 may suspend the application
564 based on information from the Window Management Module 532.
Suspending the application 564 may maintain application data in memory
but may limit or stop the application 564 from rendering a window or user
interface. Once the application becomes active again, the Task Management
module 540 can again trigger the application to render its user
interface. In embodiments, if a task is suspended, the task may save the
task's state in case the task is terminated. In the suspended state, the
application task may not receive input because the application window is
not visible to the user.

[0175] The frame buffer 548 is a logical structure(s) used to render the
user interface. The frame buffer 548 can be created and destroyed by the
OS kernel 518. However, the Display Controller 544 can write the image
data, for the visible windows, into the frame buffer 548. A frame buffer
548 can be associated with one screen or multiple screens. The
association of a frame buffer 548 with a screen can be controlled
dynamically by interaction with the OS kernel 518. A composite display
may be created by associating multiple screens with a single frame buffer
548. Graphical data used to render an application's window user interface
may then be written to the single frame buffer 548, for the composite
display, which is output to the multiple screens 104,108. The Display
Controller 544 can direct an application's user interface to a portion of
the frame buffer 548 that is mapped to a particular display 110,114,
thus, displaying the user interface on only one screen 104 or 108. The
Display Controller 544 can extend the control over user interfaces to
multiple applications, controlling the user interfaces for as many
displays as are associated with a frame buffer 548 or a portion thereof.
This approach compensates for the multiple physical screens 104,108 that
are in use by the software component above the Display Controller 544.

[0176] The Application Manager 562 is an application that provides a
presentation layer for the window environment. Thus, the Application
Manager 562 provides the graphical model for rendering by the Task
Management Module 540. Likewise, the Desktop 566 provides the
presentation layer for the Application Store 560. Thus, the desktop
provides a graphical model of a surface having selectable application
icons for the Applications 564 in the Application Store 560 that can be
provided to the Window Management Module 556 for rendering.

[0177] Further, the framework can include an Application Model Manager
(AMM) 542. The Application Manager 562 may interface with the AMM 542. In
embodiments, the AMM 542 receives state change information from the
device 100 regarding the state of applications (which are running or
suspended). The AMM 542 can associate bit map images from the Surface
Cache Module 528 to the tasks that are alive (running or suspended).
Further, the AMM 542 can convert the logical window stack maintained in
the Task Manager Module 540 to a linear ("film strip" or "deck of cards")
organization that the user perceives when the using the off gesture
capture area 120 to sort through the windows. Further, the AMM 542 may
provide a list of executing applications to the Application Manager 562.

[0178] An embodiment of the MDM module 524 is shown in FIG. 5B. The MDM
module 524 is operable to determine the state of the environment for the
device, including, but not limited to, the orientation of the device,
whether the device 100 is opened or closed, what applications 564 are
executing, how the applications 564 are to be displayed, what actions the
user is conducting, the tasks being displayed, etc. To configure the
display, the MDM module 524 interprets these environmental factors and
determines a display configuration, as described in conjunction with
FIGS. 6A-6J. Then, the MDM module 524 can bind the applications 564 or
other device components to the displays. The configuration may then be
sent to the Display Controller 544 and/or the other components within the
OS 516 to generate the display. The MDM module 524 can include one or
more of, but is not limited to, a Display Configuration Module 568, a
Preferences Module 572, a Device State Module 574, a Gesture Module 576,
a Requirements Module 580, an Event Module 584, and/or a Binding Module
588.

[0179] The Display Configuration Module 568 determines the layout for the
display. In embodiments, the Display Configuration Module 568 can
determine the environmental factors. The environmental factors may be
received from one or more other MDM modules 524 or from other sources.
The Display Configuration Module 568 can then determine from the list of
factors the best configuration for the display. Some embodiments of the
possible configurations and the factors associated therewith are
described in conjunction with FIGS. 6A-6F.

[0180] The Preferences Module 572 is operable to determine display
preferences for an application 564 or other component. For example, an
application can have a preference for Single or Dual displays. The
Preferences Module 572 can determine an application's display preference
(e.g., by inspecting the application's preference settings) and may allow
the application 564 to change to a mode (e.g., single screen, dual
screen, max, etc.) if the device 100 is in a state that can accommodate
the preferred mode. However, some user interface policies may disallow a
mode even if the mode is available. As the configuration of the device
changes, the preferences may be reviewed to determine if a better display
configuration can be achieved for an application 564.

[0181] The Device State Module 574 is operable to determine or receive the
state of the device. The state of the device can be as described in
conjunction with FIGS. 3A and 3B. The state of the device can be used by
the Display Configuration Module 568 to determine the configuration for
the display. As such, the Device State Module 574 may receive inputs and
interpret the state of the device. The state information is then provided
to the Display Configuration Module 568.

[0182] The Gesture Module 576 is shown as part of the MDM module 524, but,
in embodiments, the Gesture module 576 may be a separate Framework 520
component that is separate from the MDM module 524. In embodiments, the
Gesture Module 576 is operable to determine if the user is conducting any
actions on any part of the user interface. In alternative embodiments,
the Gesture Module 576 receives user interface actions from the
configurable area 112,116 only. The Gesture Module 576 can receive touch
events that occur on the configurable area 112,116 (or possibly other
user interface areas) by way of the Input Management Module 536 and may
interpret the touch events (using direction, speed, distance, duration,
and various other parameters) to determine what kind of gesture the user
is performing. When a gesture is interpreted, the Gesture Module 576 can
initiate the processing of the gesture and, by collaborating with other
Framework 520 components, can manage the required window animation. The
Gesture Module 576 collaborates with the Application Model Manager 542 to
collect state information with respect to which applications are running
(active or paused) and the order in which applications must appear when a
user gesture is performed. The Gesture Module 576 may also receive
references to bitmaps (from the Surface Cache Module 528) and live
windows so that when a gesture occurs it can instruct the Display
Controller 544 how to move the window(s) across the display 110,114.
Thus, suspended applications may appear to be running when those windows
are moved across the display 110,114.

[0183] Further, the Gesture Module 576 can receive task information either
from the Task Manage Module 540 or the Input Management module 536. The
gestures may be as defined in conjunction with FIGS. 4A through 4H. For
example, moving a window causes the display to render a series of display
frames that illustrate the window moving. The gesture associated with
such user interface interaction can be received and interpreted by the
Gesture Module 576. The information about the user gesture is then sent
to the Task Management Module 540 to modify the display binding of the
task.

[0184] The Requirements Module 580, similar to the Preferences Module 572,
is operable to determine display requirements for an application 564 or
other component. An application can have a set display requirement that
must be observed. Some applications require a particular display
orientation. For example, the application "Angry Birds" can only be
displayed in landscape orientation. This type of display requirement can
be determined or received, by the Requirements Module 580. As the
orientation of the device changes, the Requirements Module 580 can
reassert the display requirements for the application 564. The Display
Configuration Module 568 can generate a display configuration that is in
accordance with the application display requirements, as provided by the
Requirements Module 580.

[0185] The Event Module 584, similar to the Gesture Module 576, is
operable to determine one or more events occurring with an application or
other component that can affect the user interface. Thus, the Event
Module 584 can receive event information either from the event buffer 556
or the Task Management module 540. These events can change how the tasks
are bound to the displays. The Event Module 584 can collect state change
information from other Framework 520 components and act upon that state
change information. In an example, when the phone is opened or closed or
when an orientation change has occurred, a new message may be rendered in
a secondary screen. The state change based on the event can be received
and interpreted by the Event Module 584. The information about the events
then may be sent to the Display Configuration Module 568 to modify the
configuration of the display.

[0186] The Binding Module 588 is operable to bind the applications 564 or
the other components to the configuration determined by the Display
Configuration Module 568. A binding associates, in memory, the display
configuration for each application with the display and mode of the
application. Thus, the Binding Module 588 can associate an application
with a display configuration for the application (e.g. landscape,
portrait, multi-screen, etc.). Then, the Binding Module 588 may assign a
display identifier to the display. The display identifier associated the
application with a particular display of the device 100. This binding is
then stored and provided to the Display Controller 544, the other
components of the OS 516, or other components to properly render the
display. The binding is dynamic and can change or be updated based on
configuration changes associated with events, gestures, state changes,
application preferences or requirements, etc.

[0187] User Interface Configurations:

[0188] With reference now to FIGS. 6A-J, various types of output
configurations made possible by the device 100 will be described
hereinafter.

[0189] FIGS. 6A and 6B depict two different output configurations of the
device 100 being in a first state. Specifically, FIG. 6A depicts the
device 100 being in a closed portrait state 304 where the data is
displayed on the primary screen 104. In this example, the device 100
displays data via the touch sensitive display 110 in a first portrait
configuration 604. As can be appreciated, the first portrait
configuration 604 may only display a desktop or operating system home
screen. Alternatively, one or more windows may be presented in a portrait
orientation while the device 100 is displaying data in the first portrait
configuration 604.

[0190]FIG. 6B depicts the device 100 still being in the closed portrait
state 304, but instead data is displayed on the secondary screen 108. In
this example, the device 100 displays data via the touch sensitive
display 114 in a second portrait configuration 608.

[0191] It may be possible to display similar or different data in either
the first or second portrait configuration 604, 608. It may also be
possible to transition between the first portrait configuration 604 and
second portrait configuration 608 by providing the device 100 a user
gesture (e.g., a double tap gesture), a menu selection, or other means.
Other suitable gestures may also be employed to transition between
configurations. Furthermore, it may also be possible to transition the
device 100 from the first or second portrait configuration 604, 608 to
any other configuration described herein depending upon which state the
device 100 is moved.

[0192] An alternative output configuration may be accommodated by the
device 100 being in a second state. Specifically, FIG. 6c depicts a third
portrait configuration where data is displayed simultaneously on both the
primary screen 104 and the secondary screen 108. The third portrait
configuration may be referred to as a Dual-Portrait (PD) output
configuration. In the PD output configuration, the touch sensitive
display 110 of the primary screen 104 depicts data in the first portrait
configuration 604 while the touch sensitive display 114 of the secondary
screen 108 depicts data in the second portrait configuration 608. The
simultaneous presentation of the first portrait configuration 604 and the
second portrait configuration 608 may occur when the device 100 is in an
open portrait state 320. In this configuration, the device 100 may
display one application window in one display 110 or 114, two application
windows (one in each display 110 and 114), one application window and one
desktop, or one desktop. Other configurations may be possible. It should
be appreciated that it may also be possible to transition the device 100
from the simultaneous display of configurations 604, 608 to any other
configuration described herein depending upon which state the device 100
is moved. Furthermore, while in this state, an application's display
preference may place the device into bilateral mode, in which both
displays are active to display different windows in the same application.
For example, a Camera application may display a viewfinder and controls
on one side, while the other side displays a mirrored preview that can be
seen by the photo subjects. Games involving simultaneous play by two
players may also take advantage of bilateral mode.

[0193] FIGS. 6D and 6E depicts two further output configurations of the
device 100 being in a third state. Specifically, FIG. 6D depicts the
device 100 being in a closed landscape state 340 where the data is
displayed on the primary screen 104. In this example, the device 100
displays data via the touch sensitive display 110 in a first landscape
configuration 612. Much like the other configurations described herein,
the first landscape configuration 612 may display a desktop, a home
screen, one or more windows displaying application data, or the like.

[0194] FIG. 6E depicts the device 100 still being in the closed landscape
state 340, but instead data is displayed on the secondary screen 108. In
this example, the device 100 displays data via the touch sensitive
display 114 in a second landscape configuration 616. It may be possible
to display similar or different data in either the first or second
portrait configuration 612, 616. It may also be possible to transition
between the first landscape configuration 612 and second landscape
configuration 616 by providing the device 100 with one or both of a twist
and tap gesture or a flip and slide gesture. Other suitable gestures may
also be employed to transition between configurations. Furthermore, it
may also be possible to transition the device 100 from the first or
second landscape configuration 612, 616 to any other configuration
described herein depending upon which state the device 100 is moved.

[0195]FIG. 6F depicts a third landscape configuration where data is
displayed simultaneously on both the primary screen 104 and the secondary
screen 108. The third landscape configuration may be referred to as a
Dual-Landscape (LD) output configuration. In the LD output configuration,
the touch sensitive display 110 of the primary screen 104 depicts data in
the first landscape configuration 612 while the touch sensitive display
114 of the secondary screen 108 depicts data in the second landscape
configuration 616. The simultaneous presentation of the first landscape
configuration 612 and the second landscape configuration 616 may occur
when the device 100 is in an open landscape state 340. It should be
appreciated that it may also be possible to transition the device 100
from the simultaneous display of configurations 612, 616 to any other
configuration described herein depending upon which state the device 100
is moved.

[0196] FIGS. 6G and 6H depict two views of a device 100 being in yet
another state. Specifically, the device 100 is depicted as being in an
easel state 312. FIG. 6G shows that a first easel output configuration
618 may be displayed on the touch sensitive display 110. FIG. 6H shows
that a second easel output configuration 620 may be displayed on the
touch sensitive display 114. The device 100 may be configured to depict
either the first easel output configuration 618 or the second easel
output configuration 620 individually. Alternatively, both the easel
output configurations 618, 620 may be presented simultaneously. In some
embodiments, the easel output configurations 618, 620 may be similar or
identical to the landscape output configurations 612, 616. The device 100
may also be configured to display one or both of the easel output
configurations 618, 620 while in a modified easel state 316. It should be
appreciated that simultaneous utilization of the easel output
configurations 618, 620 may facilitate two-person games (e.g.,
Battleship®, chess, checkers, etc.), multi-user conferences where two
or more users share the same device 100, and other applications. As can
be appreciated, it may also be possible to transition the device 100 from
the display of one or both configurations 618, 620 to any other
configuration described herein depending upon which state the device 100
is moved.

[0197] FIG. 6I depicts yet another output configuration that may be
accommodated while the device 100 is in an open portrait state 320.
Specifically, the device 100 may be configured to present a single
continuous image across both touch sensitive displays 110, 114 in a
portrait configuration referred to herein as a Portrait-Max (PMax)
configuration 624. In this configuration, data (e.g., a single image,
application, window, icon, video, etc.) may be split and displayed
partially on one of the touch sensitive displays while the other portion
of the data is displayed on the other touch sensitive display. The Pmax
configuration 624 may facilitate a larger display and/or better
resolution for displaying a particular image on the device 100. Similar
to other output configurations, it may be possible to transition the
device 100 from the Pmax configuration 624 to any other output
configuration described herein depending upon which state the device 100
is moved.

[0198]FIG. 6J depicts still another output configuration that may be
accommodated while the device 100 is in an open landscape state 348.
Specifically, the device 100 may be configured to present a single
continuous image across both touch sensitive displays 110, 114 in a
landscape configuration referred to herein as a Landscape-Max (LMax)
configuration 628. In this configuration, data (e.g., a single image,
application, window, icon, video, etc.) may be split and displayed
partially on one of the touch sensitive displays while the other portion
of the data is displayed on the other touch sensitive display. The Lmax
configuration 628 may facilitate a larger display and/or better
resolution for displaying a particular image on the device 100. Similar
to other output configurations, it may be possible to transition the
device 100 from the Lmax configuration 628 to any other output
configuration described herein depending upon which state the device 100
is moved.

[0199] The device 100 manages desktops and/or windows with at least one
window stack 700, 728, as shown in FIGS. 7A and 7B. A window stack 700,
728 is a logical arrangement of active and/or inactive windows for a
multi-screen device. For example, the window stack 700, 728 may be
logically similar to a deck of cards, where one or more windows or
desktops are arranged in order, as shown in FIGS. 7A and 7B. An active
window is a window that is currently being displayed on at least one of
the touch sensitive displays 110, 114. For example, windows 104 and 108
are active windows and are displayed on touch sensitive displays 110 and
114. An inactive window is a window that was opened and displayed but is
now "behind" an active window and not being displayed. In embodiments, an
inactive window may be for an application that is suspended, and thus,
the window is not displaying active content. For example, windows 712,
716, 720, and 724 are inactive windows.

[0200] A window stack 700, 728 may have various arrangements or
organizational structures. In the embodiment shown in FIG. 7A, the device
100 includes a first stack 760 associated with a first touch sensitive
display 110 and a second stack associated with a second touch sensitive
display 114. Thus, each touch sensitive display 110, 114 can have an
associated window stack 760, 764. These two window stacks 760, 764 may
have different numbers of windows arranged in the respective stacks 760,
764. Further, the two window stacks 760, 764 can also be identified
differently and managed separately. Thus, the first window stack 760 can
be arranged in order from a first window 704 to a next window 720 to a
last window 724 and finally to a desktop 722, which, in embodiments, is
at the "bottom" of the window stack 760. In embodiments, the desktop 722
is not always at the "bottom" as application windows can be arranged in
the window stack below the desktop 722, and the desktop 722 can be
brought to the "top" of a stack over other windows during a desktop
reveal Likewise, the second stack 764 can be arranged from a first window
708 to a next window 712 to a last window 716, and finally to a desktop
718, which, in embodiments, is a single desktop area, with desktop 722,
under all the windows in both window stack 760 and window stack 764. A
logical data structure for managing the two window stacks 760, 764 may be
as described in conjunction with FIG. 8.

[0201] Another arrangement for a window stack 728 is shown in FIG. 7B. In
this embodiment, there is a single window stack 728 for both touch
sensitive displays 110, 114. Thus, the window stack 728 is arranged from
a desktop 758 to a first window 744 to a last window 756. A window can be
arranged in a position among all windows without an association to a
specific touch sensitive display 110, 114. In this embodiment, a window
is in the order of windows. Further, at least one window is identified as
being active. For example, a single window may be rendered in two
portions 732 and 736 that are displayed on the first touch sensitive
screen 110 and the second touch sensitive screen 114. The single window
may only occupy a single position in the window stack 728 although it is
displayed on both displays 110, 114.

[0202] Yet another arrangement of a window stack 760 is shown in FIGS. 7C
through 7E. The window stack 760 is shown in three "elevation" views. In
FIG. 7c, the top of the window stack 760 is shown. Two sides of the
window stack 760 are shown in FIGS. 7D and 7E. In this embodiment, the
window stack 760 resembles a stack of bricks. The windows are stacked on
each other. Looking from the top of the window stack 760 in FIG. 7c, only
the top most windows in the window stack 760 are seen in different
portions of the composite display 764. The composite display 764
represents a logical model for the entire display area of the device 100,
which can include touch sensitive display 110 and touch sensitive display
114. A desktop 786 or a window can occupy part or all of the composite
display 764.

[0203] In the embodiment shown, the desktop 786 is the lowest display or
"brick" in the window stack 760. Thereupon, window 1 782, window 2 782,
window 3 768, and window 4 770 are layered. Window 1 782, window 3 768,
window 2 782, and window 4 770 only occupy a portion of the composite
display 764. Thus, another part of the stack 760 includes window 8 774
and windows 5 through 7 shown in section 790. Only the top window in any
portion of the composite display 764 is actually rendered and displayed.
Thus, as shown in the top view in FIG. 7c, window 4 770, window 8 774,
and window 3 768 are displayed as being at the top of the display in
different portions of the window stack 760. A window can be dimensioned
to occupy only a portion of the composite display 760 to "reveal" windows
lower in the window stack 760. For example, window 3 768 is lower in the
stack than both window 4 770 and window 8 774 but is still displayed. A
logical data structure to manage the window stack can be as described in
conjunction with FIG. 8.

[0204] When a new window is opened, the newly activated window is
generally positioned at the top of the stack. However, where and how the
window is positioned within the stack can be a function of the
orientation of the device 100, the context of what programs, functions,
software, etc. are being executed on the device 100, how the stack is
positioned when the new window is opened, etc. To insert the window in
the stack, the position in the stack for the window is determined and the
touch sensitive display 110, 114 to which the window is associated may
also be determined. With this information, a logical data structure for
the window can be created and stored. When user interface or other events
or tasks change the arrangement of windows, the window stack(s) can be
changed to reflect the change in arrangement. It should be noted that
these same concepts described above can be used to manage the one or more
desktops for the device 100.

[0205] A logical data structure 800 for managing the arrangement of
windows or desktops in a window stack is shown in FIG. 8. The logical
data structure 800 can be any data structure used to store data whether
an object, record, file, etc. The logical data structure 800 can be
stored in any type of database or data storage system, regardless of
protocol or standard. In embodiments, the logical data structure 800
includes one or more portions, fields, attributes, etc. that store data
in a logical arrangement that allows for easy storage and retrieval of
the information. Hereinafter, these one or more portions, fields,
attributes, etc. shall be described simply as fields. The fields can
store data for a window identifier 804, dimensions 808, a stack position
identifier 812, a display identifier 816, and/or an active indicator 820.
Each window in a window stack can have an associated logical data
structure 800. While only a single logical data structure 800 is shown in
FIG. 8, there may be more or fewer logical data structures 800 used with
a window stack (based on the number of windows or desktops in the stack),
as represented by ellipses 824. Further, there may be more or fewer
fields than those shown in FIG. 8, as represented by ellipses 828.

[0206] A window identifier 804 can include any identifier (ID) that
uniquely identifies the associated window in relation to other windows in
the window stack. The window identifier 804 can be a globally unique
identifier (GUID), a numeric ID, an alphanumeric ID, or other type of
identifier. In embodiments, the window identifier 804 can be one, two, or
any number of digits based on the number of windows that can be opened.
In alternative embodiments, the size of the window identifier 804 may
change based on the number of windows opened. While the window is open,
the window identifier 804 may be static and remain unchanged.

[0207] Dimensions 808 can include dimensions for a window in the composite
display 760. For example, the dimensions 808 can include coordinates for
two or more corners of the window or may include one coordinate and
dimensions for the width and height of the window. These dimensions 808
can delineate what portion of the composite display 760 the window may
occupy, which may the entire composite display 760 or only part of
composite display 760. For example, window 4 770 may have dimensions 880
that indicate that the window 770 will occupy only part of the display
area for composite display 760, as shown in FIGS. 7c through 7E. As
windows are moved or inserted in the window stack, the dimensions 808 may
change.

[0208] A stack position identifier 812 can be any identifier that can
identify the position in the stack for the window or may be inferred from
the window's control record within a data structure, such as a list or a
stack. The stack position identifier 812 can be a GUID, a numeric ID, an
alphanumeric ID, or other type of identifier. Each window or desktop can
include a stack position identifier 812. For example, as shown in FIG.
7A, window 1 704 in stack 1 760 can have a stack position identifier 812
of 1 identifying that window 704 is the first window in the stack 760 and
the active window. Similarly, window 6 724 can have a stack position
identifier 812 of 3 representing that window 724 is the third window in
the stack 760. Window 2 708 can also have a stack position identifier 812
of 1 representing that window 708 is the first window in the second stack
764. As shown in FIG. 7B, window 1 744 can have a stack position
identifier 812 of 1, window 3, rendered in portions 732 and 736, can have
a stack position identifier 812 of 3, and window 6 756 can have a stack
position identifier 812 of 6. Thus, depending on the type of stack, the
stack position identifier 812 can represent a window's location in the
stack.

[0209] A display identifier 816 can identify that the window or desktop is
associated with a particular display, such as the first display 110 or
the second display 114, or the composite display 760 composed of both
displays. While this display identifier 816 may not be needed for a
multi-stack system, as shown in FIG. 7A, the display identifier 816 can
indicate whether a window in the serial stack of FIG. 7B is displayed on
a particular display. Thus, window 3 may have two portions 732 and 736 in
FIG. 7B. The first portion 732 may have a display identifier 816 for the
first display while the second portion 736 may have a display identifier
816 for the second display 114. However, in alternative embodiments, the
window may have two display identifier 816 that represent that the window
is displayed on both of the displays 110, 114, or a display identifier
816 identifying the composite display. In another alternate embodiment,
the window may have a single display identifier 816 to represent that the
window is displayed on both of the displays 110, 114.

[0210] Similar to the display identifier 816, an active indicator 820 may
not be needed with the dual stack system of FIG. 7A, as the window in
stack position 1 is active and displayed. In the system of FIG. 7B, the
active indicator 820 can indicate which window(s) in the stack is being
displayed. Thus, window 3 may have two portions 732 and 736 in FIG. 7.
The first portion 732 may have an active indicator 820 while the second
portion 736 may also have an active indicator 820. However, in
alternative embodiments, window 3 may have a single active indicator 820.
The active indicator 820 can be a simple flag or bit that represents that
the window is active or displayed.

[0211] An embodiment of a method 900 for creating a window stack is shown
in FIG. 9. While a general order for the steps of the method 900 is shown
in FIG. 9. Generally, the method 900 starts with a start operation 904
and ends with an end operation 928. The method 900 can include more or
fewer steps or can arrange the order of the steps differently than those
shown in FIG. 9. The method 900 can be executed as a set of
computer-executable instructions executed by a computer system and
encoded or stored on a computer readable medium. Hereinafter, the method
900 shall be explained with reference to the systems, components,
modules, software, data structures, user interfaces, etc. described in
conjunction with FIGS. 1-8.

[0212] A multi-screen device 100 can receive activation of a window, in
step 908. In embodiments, the multi-screen device 100 can receive
activation of a window by receiving an input from the touch sensitive
display 110 or 114, the configurable area 112 or 116, a gesture capture
region 120 or 124, or some other hardware sensor operable to receive user
interface inputs. The processor may execute the Task Management Module
540 may receive the input. The Task Management Module 540 can interpret
the input as requesting an application task to be executed that will open
a window in the window stack.

[0213] In embodiments, the Task Management Module 540 places the user
interface interaction in the task stack 552 to be acted upon by the
Display Configuration Module 568 of the Multi-Display Management Module
524. Further, the Task Management Module 540 waits for information from
the Multi-Display Management Module 524 to send instructions to the
Window Management Module 532 to create the window in the window stack.

[0214] The Multi-Display Management Module 524, upon receiving instruction
from the Task Management Module 540, determines to which touch portion of
the composite display 760, the newly activated window should be
associated, in step 912. For example, window 4 770 is associated with the
a portion of the composite display 764 In embodiments, the device state
module 574 of the Multi-Display Management Module 524 may determine how
the device is oriented or in what state the device is in, e.g., open,
closed, portrait, etc. Further, the preferences module 572 and/or
requirements module 580 may determine how the window is to be displayed.
The gesture module 576 may determine the user's intentions about how the
window is to be opened based on the type of gesture and the location of
where the gesture is made.

[0215] The Display Configuration Module 568 may use the input from these
modules and evaluate the current window stack 760 to determine the best
place and the best dimensions, based on a visibility algorithm, to open
the window. Thus, the Display Configuration Module 568 determines the
best place to put the window at the top of the window stack 760, in step
916. The visibility algorithm, in embodiments, determines for all
portions of the composite display, which windows are at the top of the
stack. For example, the visibility algorithm determines that window 3
768, window 4 770, and window 8 774 are at the top of the stack 760 as
viewed in FIGS. 7C through 7E. Upon determining where to open the window,
the Display Configuration Module 568 can assign a display identifier 816
and possibly dimensions 808 to the window. The display identifier 816 and
dimensions 808 can then be sent back to the Task Management Module 540.
The Task Management Module 540 may then assign the window a stack
position identifier 812 indicating the windows position at the top of the
window stack.

[0216] In embodiments, the Task Management Module 540 sends the window
stack information and instructions to render the window to the Window
Management Module 532. The Window Management Module 532 and the Task
Management Module 540 can create the logical data structure 800, in step
924. Both the Task Management Module 540 and the Window Management Module
532 may create and manage copies of the window stack. These copies of the
window stack can be synchronized or kept similar through communications
between the Window Management Module 532 and the Task Management Module
540. Thus, the Window Management Module 532 and the Task Management
Module 540, based on the information determined by the Multi-Display
Management Module 524, can assign dimensions 808, a stack position
identifier 812 (e.g., window 1 782, window 4 770, etc.), a display
identifier 816 (e.g., touch sensitive display 1 110, touch sensitive
display 2 114, composite display identifier, etc,), and an active
indicator 820, which is generally always set when the window is at the
"top" of the stack. The logical data structure 800 may then be stored by
both the Window Management Module 532 and the Task Management Module 540.
Further, the Window Management Module 532 and the Task Management Module
540may thereinafter manage the window stack and the logical data
structure(s) 800.

[0217] An embodiment of a method 1000 for executing an application is
shown in FIG. 10. While a general order for the steps of the method 1000
is shown in FIG. 10. Generally, the method 1000 starts with a start
operation 1004 and ends with an end operation 1040. The method 1000 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 10. The method 1000 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 1000 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-48.

[0218] An application is executed, in step 1008. In embodiments, a
processor 204 receives indication to execute an application through a
user interface 110, 114, 112, 116, etc. The indication can be a selection
of an icon associated with the application. In other embodiments, the
indication can be a signal generated from another application or event,
such as receiving an e-mail or other communication, which causes the
application to execute automatically. The processor 204 can retrieve the
application 564a from the application store 560 and begin its execution.
In executing the application 564a, a user interface can be generated for
a user, as described in conjunction with FIGS. 11-61D.

[0219] In creating a user interface, the application 564a can begin
executing to create a manifest, in step 1012. A manifest is a data
structure that indicates the capabilities of the application 564a. The
manifest can generally be created from the resources in the resources
directory of the application 564a. The resources directory can indicate
the types of modes, locations, or other indications for how the user
interface should be configured in the multi-display device 100. For
example, the several modes can include: "classic mode" that indicates
that the application 564a is capable of being displayed on a single
screen or display 110/114; "dual mode" that indicates that the
application 564a is capable of being displaced on two or more displays110
and 114; "max mode" that indicates the application 564a is capable of
being displayed or desires to be displayed across multiple displays 110
and 114; and/or "bilateral mode" that indicates that the application 564a
is capable of being displayed on 2 or more displays 110 and 114 when the
device 100 is in easel mode (see FIGS. 11 and/or 1J).

[0220] Similarly, the manifest can include a desired or allowed location
within the displays 110/114. The possible locations can include: "left",
which indicates that the application 564a desires to be displayed on the
left display 110; "right", which indicates that the application 564a
desires to be displayed on the right display 114; and/or other
indications of where a location should be including possible "top" and/or
"bottom" of one or more of the displays 110/114.

[0221] The application 564a can also indicate that it desires to be
displayed in a "minimum" window, which is a window that occupies less
than the full area of a single display. There may be other modes possible
for the application 564a, which may be included in the manifest. The
manifest can be sent from the application 564a to the multi-display
management module 524.

[0222] The multi-display management module 524 can receive the manifest,
in step 1016. In receiving the manifest, the multi-display management
module 524 can use the information to determine a display binding for the
application 564a. The manifest may be received more than once from the
application 564a based on changes in how the application 564a is being
executed, where the application 564a desires to have a different display
setting for the new mode. Thus, with the manifest, the application 564a
can indicate to the multi-display management module 524 how best to or
what is the desired for the application's user interface. The
multi-display management module 524 can use the information in the
manifest to determine the best fit for the user interface depending on
how the device 100 is currently configured.

[0223] The multi-display management module 524 can determine the
application display mode, in step 1020. Here the multi-display management
module 524 receives or retrieves an indication of the device 100
configuration. For example, the multi-display management module 524 can
determine if the device is in single display configuration (see FIG. 6A,
6B, 6D, or 6E), dual display configuration (see FIG. 6c or 6F), bilateral
display configuration (see FIG. 6G or 6H), or one of the other display
configurations (see FIG. 6I or 6J).

[0224] Further, the multi-display management module 524 can determine if
the device 100 is in a portrait or landscape orientation. With this
information, the multi-display management module 524 may then consider
the capabilities or preferences listed for the application 564a in the
received manifest. The combined information may then allow the
multi-display management module 524 to determine a display binding. The
display binding can include which of the one or more displays 110 and/or
114 are going to be used to display the application's user interface(s).
For example, the multi-display management module 524 can determine that
the primary display 110, the secondary display 114, or all displays 110
and 114 of the device 100 will be used to display the application's user
interface.

[0225] The display modes setting can be assigned by creating or setting a
number in the display binding. This number can be "0" for the primary
display 110, "1" for the secondary display 114, or "2" for dual displays
110 and 114. The display mode setting can also indicate if the
application 564a should display the user interface in portrait or
landscape orientation. Further, there may be other settings, for example,
providing a max mode or other setting that may indicate how the
application 564a is to be displayed on the device. The display binding
information is stored in a data structure to create and set a binding, in
step 1024.

[0226] The established display binding may then be provided, by the
multi-display management module 524, to the application 564a, in step
1028. The provided display binding data structure can become an attribute
of the application 564a. An application 564a may thereinafter store the
display binding attribute in the memory of the device 100. The
application 564a with the display binding may then generate a user
interface based on this display binding. The application 564a may be
unaware of the position of the display 110/114 but may, from the display
binding, be able to determine the size of the available user interface to
generate a window that has particular characteristics for that display
setting.

[0227] When a configuration change happens to the device 100, the
multi-display management module 524 may change the display binding and
send a new display binding to the application 564a. In embodiments, the
multi-display management module 524 may indicate to the application 564a
that there is a new binding or, in other embodiments, the application
564a may request a display configuration change or a new display binding,
in which case the multi-display management module 524 may send a new
display binding to the application 564a. Thus, the multi-display
management module 524 can change the configuration of the display for the
application 564a by altering the display binding for the application 564a
during the execution of that application 564a.

[0228] The multi-display management module 524 thereinafter, while the
application 564a is executing, can determine if there has been a
configuration change to the device 100, in step 1032. The configuration
change may be an event (see FIG. 3A and 3B) triggered by one or more
signals from one or more hardware sensor 172, 176, etc. For example, if
the device 100 is changed from portrait 304 to landscape 340 orientation,
Hall effect sensors 172 may indicate to the framework 520 that a display
configuration change has been made. Other changes may include transitions
from a single display 304 to a dual display configuration 320, by opening
the device. Other types of configuration changes may be possible and may
be signaled to alert the multi-display management module 524 of the
configuration change. If a configuration change has been made, the method
1000 proceeds YES to step 1020 so that the multi-display management
module 524 can determine new application display mode settings and create
a new display binding, which may be passed to the application 564a. If
there are no configuration changes, the method 1000 precedes NO to step
1036.

[0229] In step 1036, a new application mode change may be determined.
Application mode changes can also occur in the application 564a, and
thus, the application 564a can determine if something has occurred within
the application 564a that requires a different display setting. Modes are
described hereinafter with respect to FIG. 12. The mode change can create
a desire to change the display 110/114, and thus, require the application
564a to generate a new manifest. If the application 564a does sense a
mode change or an event has occurred that requires a change in display
setting, the method 1000 proceeds YES back to step 1012. At step 1012, a
new manifest or preference is created by the application 564a that may be
received by the multi-display management module 524 to determine if the
multi-display management module 524 can change the display binding. If it
is possible to provide the preferred display, the multi-display
management module 524 can create a new display binding and send display
binding back to the application 564a and allow the application 564a to
alter its user interface. If no mode change is sensed or an event is not
received to create a mode change, the method 1000 proceeds NO to end
operation 1040.

[0230] An example of an image capture feature or application 1100 is shown
in FIG. 11. An image capture feature 1100 can acquire static images, such
as pictures, and/or dynamic images, such as videos. The image capture
feature 1100 can be displayed on one or more screens 110, 114 of the
device 100. The image capture feature 1100 may have one or more user
selectable buttons or icons. For example, selectable icon 1104 may be
touched to zoom into an image or to do some other function. A field 1108,
within an image capture window 1116, can display a preview of the image
that the user desires to capture. A menu or control bar 1112 can include
one or more user selectable icons or buttons to provide different
functionality to the image capture feature 1100. For example, button and
slide bar 1124 allow the user to switch from capturing pictures to
capturing video. User selectable device 1128, when selected, begins the
image acquisition whether the image is a picture or a video. Further, a
gallery 1120, showing thumbnails of previously captured pictures or
videos, may be provided on the control bar 1112. Other buttons, such as
user selectable button or icon 1132, allows the user to switch between
image capture modes, as discussed herein, such as the forward facing or
rear facing image capture modes.

[0231] In a dual screen portrait orientation, as shown in FIG. 12, the
image capture feature 1100 may include a first display 1200 and a second
display 1204. The first display 1200 may be similar or the same as that
described in FIG. 11. A second screen 1204 might provide a gallery of
recently acquired images. For example, an thumbnail or other display
feature 1208 may represent one of the recently acquired videos or images.
A set of one or more user selectable icons 1212 allow the user to conduct
functions on the image or image representation 1208.

[0232] The display 1204 may be navigable as it may be slid or be moved,
with user interface input, to view or select other images. The number of
images displayed within the user navigable display 1204 may be limited.
There may be only a select number of images that can be displayed or
selected by the user in display 1204. To view other images not currently
shown, the user may need to navigate within the display 1204 or select a
gallery function. A gallery function may be provided to view all images
that have been acquired by the image capture function 1100, as described
hereinafter.

[0233] An embodiment of a method 1300 for executing an application is
shown in FIG. 13. While a general order for the steps of the method 1300
is shown in FIG. 13. Generally, the method 1300 starts with a start
operation 1304 and ends with an end operation 1332. The method 1300 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 13. The method 1300 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 1300 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-16B.

[0234] In a first device configuration, the device 100 may have a first
screen 110 and a second screen 114 and the device 100 may be in a closed
state as described herein. In this closed state, the first and second
screens 110, 114 may face opposite directions. In a first display mode, a
first window may be provided or presented on a first screen 110. While in
this mode, the device 100 may receive an input from a user. The input
received can request the execution of image capture function 1100, in
step 1308. The device 100 can determine an image capture function 1100
configuration based on the devices state and display mode, in step 1312.
The device 100 can determine a devices orientation, in step 1316, a
device state, in step 1320, and a device image capture mode, in step
1324. Based on the determined orientation, state, and image capture mode,
the device 100 may enter an image capture mode that is presented to the
user, in step 1328.

[0235] At some time thereinafter, while remaining in the image capture
mode, the device 100 may receive an orientation change. The orientation
change can include a rotation of the device 100, the device 100 moving
from a closed state to an open state, or from an open state to a closed
state. The rotation of the device 100 may be from portrait to landscape
or from landscape to portrait, or the device 100 may be flipped such that
the screens face different directions from their original configuration.
When received, and based on the new orientation, the device 100 may
present a new image capture mode by providing a different type of display
for the image capture function 1100 1110. A least a portion of the first
and/or second screen 110, 114 change from the original display to the new
display.

[0236] A first set of modes is shown in FIGS. 14A through 16B. In FIGS.
14A through 16B, the device 100 is in a closed state and landscape
orientation. The image capture mode 1400 is to capture an outward facing
image (e.g. a scene in front of the user). Further, while in the outward
facing image mode, three or more different configurations for the image
capture feature 1100 may be presented.

[0237] For example, as shown in FIG. 14A, the second screen 114, facing
the user, shows a preview 1404 in the window 114. The control bar 1112 is
arranged vertically along the right side of the display window 1100. The
first screen 110, which faces the scene to be captured in the image, is
shown in FIG. 14B. The second display 1408 is disabled and is not
displaying anything. As such, display 1408 is is blank in this
configuration and is viewed as a black screen by anyone in front of the
user.

[0238] In a second configuration 1500 shown in FIGS. 15A and 15B, the
preview 1404 is again shown in screen 114. In contrast to FIG. 14B, an
image 1504 is displayed in the first screen 110, as shown in FIG. 15B.
The first screen 110 shows an image that looks like a camera lens to
anyone in front of the user. Thus, the party in the scene to be captured
is presented with a visual indicia that indicates a picture or image is
being taken.

[0239] Still another configuration is presented in FIGS. 16A and 16B. In
FIG. 16A, a second screen 114 again shows the preview 1404 as described
in FIGS. 14A and 15A. However, the first screen 110 also displays a
preview 1604 to the party in the scene to be captured. As such, the
preview is displayed both on the first screen 110 and the second screen
114. This configuration allows the party who is having their image taken
to preview or see what image is being captured.

[0240] These different outward facing configurations allow the user to
select different functions that are best suited for the image being
captured. For example, the dual preview screens presented in FIGS. 16A
and 16B allow a user to provide a camera to a third party and still
preview the image although they may not be taking the picture.

[0241] An embodiment of a method 1700 for executing an application is
shown in FIG. 17. While a general order for the steps of the method 1700
is shown in FIG. 17. Generally, the method 1700 starts with a start
operation 1704 and ends with an end operation 1732. The method 1700 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 17. The method 1700 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 1700 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-18.

[0242] A next mode available with the image capture function 1100 may be a
self-portrait mode. Similar to the method described in conjunction with
FIG. 13, the device 100 may receive user input to execute an image
capture function 1100, in step 1708. The input may be received in a
device 100 that has at least the first screen 110 and second screen 114.
The device 100 may then make one or more determinations. For example, the
device 100 may determine an image capture function 1100 configuration, in
step 1712. The image capture function 1100 configuration may be a
self-portrait mode. Further, the device 100 may determine the devices
orientation, in step 1716, as described herein. The device 100 may also
determine a devices state, in step 1720. From these different
determinations the device 100 may then determine that the image capture
mode is for a self-portrait, in step 1724. Based on the determination
that the device is un a self-portrait mode, the device 100 may enter the
self-portrait configuration, in step 1728.

[0243] An example of a self-portrait configuration 1800 is as shown in
FIG. 18. The device 100 configuration 1800 may provide a preview screen
1804. To limit the amount of hardware provided with the device 100, there
may be a single lens or other hardware used to capture the image, as
shown in FIGS. 1A-1J. As shown in FIG. 11, the lens 1136 is associated
with the first screen 110. Thus, to accomplish a self-portrait, the first
screen 110 must face the user. This device orientation is in contrast to
what is shown in FIGS. 14A through 16B where the lens faces away from the
user to attain an outward facing image. Further, the device 100 may be in
the closed state in landscape orientation such that the lens associated
with the screen is pointing towards the user.

[0244] The other screen 114 may be disabled. Thus, the second screen 114
cannot receive user input while the device is a self-portrait mode.
Prohibiting user input on the second screen 114 prevents inadvertent
interfere with the capture of the self-portrait. Thus, the preview 1804
and all the controls 1112 for capturing the self-image are facing the
user while nothing is displayed away from the user. The control bar 1112
is also provided in the single screen 110 with the preview 1804. Thus,
the device 100 may allow for the user to enter user interface input while
in the self-portrait mode with the screen 110 facing the user, as shown
in FIG. 18.

[0245] It should be noted that to switch between the different modes as
described in FIGS. 13 through 18, different user interfaces inputs may be
received. For example, the user interface input to change the display on
the outward facing screen, as shown in FIGS. 14A through 16B, may include
one or more inputs or gestures into a gesture capture region 120, 124, as
described herein. For example, the input can be two or more taps in the
gesture capture region 120, 124 to change the display on the outward
facing screen 110. Alternatively, the taps may be to switch from an
outward facing image to a self-portrait. The taps or the sequence of taps
may cause the device 100 to present other user interfaces or windows that
allow the user to acknowledge a desire to switch to the other screen or
change the configuration of the device 100.

[0246] The user may then select an icon or user selectable device, within
the presented window, to switch to the desired configuration where the
device 100 will execute a change of the displays in response to the
selection of the icon. The user may also select a second user interface
device in the presented window, to cancel the switch in the
configuration, and thus, acknowledge that the taps or user interface
input may be inadvertent.

[0247] Input may also be received outside the gesture capture region 120,
124 that can request a switch to a second screen 114 or change a display.
The gesture capture region 120, 124 may be on a first screen 110 and/or a
second screen 114, as described herein. The change of displays may also
include a determination of the state of the phone, such that, the state
of the phone may provide different display configurations for the image
capture function 1100. One of the device state changes, which may cause a
different display configuration, is a switch from a single screen view,
as shown in FIG. 11, to a dual screen view, as shown in FIG. 12.

[0248] An embodiment of a method 1900 for executing an application is
shown in FIG. 19. While a general order for the steps of the method 1900
is shown in FIG. 19. Generally, the method 1900 starts with a start
operation 1904 and ends with an end operation 1932. The method 1900 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 19. The method 1900 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 1900 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-20.

[0249] The device 100 may receive user input to execute the image capture
function 1100, in step 1908. The device 100 can have at least a first
screen 110 and second screen 114 and execute the image capture function
1100 upon receiving the user input. In order to determine how to display
the image capture function 1100 in the device 100, the device 100 may
determine an image capture function 1100 mode, in step 1912. The image
capture function 1100 mode 1100 can be such items as self-portrait mode,
outward facing mode, or other types of modes.

[0250] The device 100 may also determine a device orientation, in step
1916. The devices orientation may be portrait, landscape, or other types
of device configurations. The device 100 may also determine a device
state, in step 1920. The device state may include whether the device 100
is opened or closed or other types of orientations. The device
orientation and state are described further herein. Through these
different determinations, the device 100 may determine that the image
capture mode is for a dual screen configuration, in step 1924. Upon
determining that the image capture mode is a dual screen configuration,
the device 100 may enter the dual screen configuration, in step 1928.

[0251] While in the dual screen configuration, the device 100 is in an
open state and may be in a landscape or portrait orientation. An example
of the dual screen portrait orientation is shown in FIG. 12. An example
of the dual screen landscape orientation 2000 is shown in FIG. 20. The
lens 168 may be associated with either a first or second screen 110, 114
but, as an example, is shown only associated with the first screen 110,
in FIG. 20.

[0252] While in the dual screen orientation, the image capture function
1100 presents an inward facing image 2004 and may be in a self-portrait
mode. A first screen 110 may display a preview 2004 of the image to be
acquired in the self-portrait mode. The second screen 114 may provide for
a film roll 1204 that displays one or more previously acquired images.
The second screen 114 may provide a display for a last image acquired.
Thus, instead of a film roll 2008, the second display 114 may provide for
an image displayed across the entire second screen 114. In still other
configurations, a preview of an image to be acquired may be presented
across both the first and second screens 110, 114, such that the image is
larger than what is normally shown in the a single screen view.

[0253] An embodiment of a method 2100 for executing an application is
shown in FIG. 21. While a general order for the steps of the method 2100
is shown in FIG. 21. Generally, the method 2100 starts with a start
operation 2104 and ends with an end operation 2124. The method 2100 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 21. The method 2100 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 2100 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-20.

[0254] While in the dual screen mode, device orientation changes may be
received. For example, the dual screen orientation as shown in FIG. 12
may change to that shown in FIG. 20 when the device 100 is rotated either
clockwise or counterclockwise. Thus, the device 100 may receive a user
input to execute an image capture function 1100, in step 2108. A first
display 1200 may be presented for the image capture function 1100, in
step 2112, as described hereinbefore in FIGS. 13 through 19. After
presenting the first display 1200 for the image capture function 1100,
the device 100 may receive a rotation of the device 100, in step 2116. In
response to the rotation of the device 100, the device 100 may present a
second display 2000 for the image capture function 1100 that is different
from the first display 1200, in step 2120.

[0255] The image capturing function may be configured to be in a dual
screen orientation capturing an inward facing image, as shown in FIG. 12.
Thus, the device 100 is in an open state and the first display 1200 is in
a portrait orientation. With the rotation, the display can change to a
landscape orientation 2000, as shown in FIG. 20. One or more portions of
the display may change due to the rotation. For example, the preview
image 1108, shown in FIG. 12, changes to a landscape orientation 2004,
shown in FIG. 20.

[0256] Likewise, the film roll 1204, shown in FIG. 12, changes to a
landscape orientation 2008, shown in FIG. 20. As the film roll 1204, 2008
is navigable, the film roll 2008 may now move horizontally rather than
vertically along the long axis of the screen 114, thus the film roll 2008
changes movement from a vertical orientation to a horizontal orientation.
Further, the images within the film roll 2008 may change from a portrait
orientation to a landscape orientation.

[0257] Unlike the preview 1200 or the film roll 1204, the camera controls
shown in the control area 1112 may be in a fixed position, as shown in
FIG. 20. The image preview 2004 may remain in the first screen 110 while
changing the device's orientation during the rotation of the device 100.
Thus, the device 100 can change the look and feel of the dual screen
display when the device 100 is rotated from a portrait orientation shown
in FIG. 12 to a landscape orientation of FIG. 20. It should be noted too
that the device 100 may be rotated back to the portrait orientation in
FIG. 12, where the changes are reversed and the display is as shown in
FIG. 12.

[0258] An embodiment of a method 2200 for executing an application is
shown in FIG. 22. While a general order for the steps of the method 2200
is shown in FIG. 22. Generally, the method 2200 starts with a start
operation 2204 and ends with an end operation 2224. The method 2200 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 22. The method 2200 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 2200 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-21.

[0259] The method 2200 begins by providing a device 100 having at least a
first screen 110 and second screen 114. The device 100 can be as
described in conjunction with FIGS. 1A through FIG. 10. The device 100,
through a user interface input or other input, can receive a directive or
request to execute a gallery function, in step 2208.

[0260] A gallery 3000 may be as shown in FIG. 30. A gallery 3000 is any
type of user interface that allows a user to manage, view, select,
delete, or do other functions with images captured or stored on the
device 100. A gallery 3000 can contain one or more thumbnail images 3004
in a display. A thumbnail can be any representation of an image stored or
captured by the device 100 that is presented in a smaller form or size.
An image can be a picture or video. A thumbnail for a video may be
created from a single frame of the video.

[0261] The device 100 can receive a first input to execute a full screen
view of an image, in step 2212. For example, a user may view an image
2304 selected in a gallery 3000 as shown in FIG. 23. This image 2304 may
be shown with one or more different controls, icons, or user interface
devices 2308. The user may select one of the user interface devices 2312
to view the image as a full screen image. Upon receiving the input the
device 100 may then show the image 2304 in a full screen as shown in FIG.
24. Here, the image 2304 spans the entire width or the entire height of
the available screen 110. One or more user icons may also be shown 2408
that allow the user to manage the image 2304 or exit the full screen
view.

[0262] Thereinafter, a second input may be received by the device 100 that
changes the state of the device 100 from a closed state to an open state,
in step 2216. For example, the device 100 may go from a view as shown in
FIG. 24 to that shown in FIG. 25. As shown in FIG. 25, the device 100 is
now in an open state where both screens 110, 114 are viewed. In response
to the change from the closed state to the open state, the device 100 may
then display the image 2304 in at least a portion of the first screen 110
and at least a portion of the second screen 114, in step 2220. For
example, image 2304 has expanded to cover both the screen 110 and the
screen 114. Thus, a change in state for the device 100, while viewing an
image 2304 in full screen, allows the user to use both screens 110, 114
to better see a larger more detailed image. The change in the state the
device 100 increases the size of the image to expand into a view that
covers at least a portion of the first screen 110 and second screen 114
110, 114.

[0263] As shown in FIGS. 24 and 25, the device 100 can be in a landscape
orientation when viewing the image 2304, and the second input opens the
device 100 into a dual screen landscape orientation. It should be noted
that the device 100 may be in a portrait orientation when opened, and the
device 100 state can be changed to a dual screen portrait orientation. In
some instances, a portion of the image that was not displayed while in
the closed state may be displayed in the dual screen landscape/portrait
orientation. When in a dual screen landscape orientation, the image 2304
may be centered across the first screen 110 and second screen 114, such
that the image 2304 is displayed in the middle of the display area
horizontally and/or vertically.

[0264] As explained earlier, the device 100 may be in a portrait
orientation when in a closed state, and the second input that opens the
device 100 changes the device orientation to a dual screen portrait
orientation. For example, FIG. 26 may provide a display that shows an
image 2604 stored in a gallery 3000. A user may select a user interface
device 2608 to view the image 2604 on a full screen. Upon selecting that
input, the user may be presented with the display 2704 shown in FIG. 27.

[0265] After viewing this image 2704 in the full screen, the user may then
open the device 100 and change the orientation of the device 100 from a
closed portrait orientation to a dual screen portrait orientation as
shown in FIG. 28. Similar to the dual screen landscape orientation at
least a portion of the image 2704 may be displayed in the dual screen
portrait orientation that was not shown when the device 100 was in the
closed state. For example, a bottom portion 2808 of the image shown in
FIG. 28 is not shown in FIG. 27 in the portion 2708.

[0266] Upon receiving the first input to display the image 2704 in a full
screen the gallery 3000 may provide one or more user selectable icons
2712 and 2716 associated with the gallery function to allow the user to
manage the image 2704 displayed in the full screen. When the second input
is received and in response to the second input, the display of the user
selectable icons 2712 and 2716 may change position. For example, icons
2712 and 2716 are displayed at a bottom right hand corner of a first
display 110 in FIG. 27. Upon changing the device 100 configuration to the
open state, the user selectable icons 2712 and 2716 are moved to a bottom
right hand portion of a second screen 114 in the full screen view of the
image. This change may also be shown or seen when going from the
landscape closed state to the dual screen landscape orientation. In
embodiments, the screen or display size may not cover an entire display
area. For example, image 2704 may not expand into display areas 2820 or
2824.

[0267] An embodiment of a method 2900 for executing an application is
shown in FIG. 29. While a general order for the steps of the method 2900
is shown in FIG. 29. Generally, the method 2900 starts with a start
operation 2904 and ends with an end operation 2916. The method 2900 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 29. The method 2900 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 2900 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-28.

[0268] Method 2900 may also begin by providing a device 100 that has a
first screen 110 and a second screen 114. The device 100 may be in a
landscape dual screen orientation, as shown in FIG. 30. The device 100
may receive a first input to execute a gallery function, in step 2908.
The input can be a user interface input received from a user or some
other directive from an application executing on the device 100. For
example, an e-mail program that desires to download an image into an
e-mail may send a directive to open a gallery 3000 that allows the user
to select a picture from the gallery 3000 to put in an e-mail. In
response to the first input, a gallery 3000 may be displayed over at
least a portion of the first screen 110 and at least a portion of the
second screen 114, in step 2912.

[0269] An example of the gallery 3000 is shown in FIG. 30. The gallery
3000 is displayed across or at least in a portion of first screen 110 and
a second screen 114. This allows the thumbnails 3004, to have a larger
area to be displayed. Further, the gallery 3000 may be able to display
more thumbnails 3004 within the space provided by extending the gallery
3000 over the first screen 110 and the second screen 114.

[0270] The gallery 3000 can include a first section 3012 and a second
section 3016. The first section 3012 of the gallery 3000 may display one
or more albums 3020 and 3024. An album is a collection of images
associated with each other and/or stored as a group. The albums may be
selected to filter the number of images shown in the second section 3016.

[0271] The first section 3012 of the gallery 3000 is navigable. In other
words, the user may have more albums available than can be shown in the
first section 3012. Thus, the user can scroll or move the display to view
other albums not shown presently on the display. For example, the user
may use a drag function by dragging their finger across the first section
3012 to move or scroll the first section 3012 of the gallery 3000.

[0272] The second section 3016 can provide a grid that displays one or
more image thumbnails 3004 that are associated with images in either an
album 3020, 3024 or in the gallery 3000. An image thumbnail 3004 is a
representation of an image that may be smaller than the original image.
For example, image thumbnails 3004 can be a smaller version of the actual
image stored in the device 100. The thumbnail 3004 allows the user to see
a preview of the image and manage the image by knowing what was in the
image file.

[0273] The second portion 3016 of the gallery 3000 may be viewed or
displayed across a portion of the first screen 110 and the second screen
114. Thus, the grid can use substantially all available display space
below or next to the first section 3012 Like the first section 3012, the
second section 3016 may also be navigable. As more images may be stored
in the device 100 than are able to be displayed within the available
display space of the second section 3016, the grid may be moved or
scrolled using user interface inputs similar to those explained in
association with section 3012.

[0274] The gallery 3000 may also include an action bar 3028 that can
include one or more user selectable icons for executing one or more
functions associated with the gallery 3000. For example, user selectable
icon 3032 may allow the user to share an image selected within the
gallery 3000 through another application, such as Twitter, e-mail, or
other social media application. As a further example, user selectable
icon 3036 may be selected to delete or erase an image selected within the
gallery 3000.

[0275] In selecting an album in the first section 3012, the display grid
in the second section 3016 may change which images are displayed in the
grid. Alternatively, the display may change how the images are displayed.
Regardless, when selecting an album 3020, 3024, the device 100 may change
how the gallery functions or provides information to the user. For
example, as shown in FIG. 31, the gallery 3000 has an album 3020
selected. Upon selecting the album 3020, the first section 3012 may be
darkened. Further, the second section 3016 may be shown with one or more
images 3104 having a checkmark. The checkmark may be an indication that
that image(s) is associated with the album 3020 selected in the first
section 3012. Alternatively, only the images that are associated with the
album are shown in the grid in the second section 3016. Thus, the device
100 may receive a selection of an album 3020 in the first section 3012.
In response to the selection of the album, the device 100 can change the
display of the grid to include one or more images associated with the
album. Images not associated with the album may not be displayed in the
grid.

[0276] An embodiment of a method 3200 for executing an application is
shown in FIG. 32. While a general order for the steps of the method 3200
is shown in FIG. 32. Generally, the method 3200 starts with a start
operation 3204 and ends with an end operation 3224. The method 3200 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 32. The method 3200 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 3200 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-31.

[0277] Method 3200 also provides for a device 100 with a first screen 110
and second screen 114. The device 100 may be in a landscape dual screen
orientation. The device 100 may receive a first input to execute a
gallery function, in step 3208. In response to the first input, the
device 100 can display the gallery 3000 across at least a portion of the
first screen 110 and at least a portion of the second screen 114, in step
3212.

[0278] Thereinafter, the device 100 can receive a selection of an album in
the gallery 3000, in step 3216, as described in conjunction with FIGS. 29
through 31. In response to the selection of the album, the device 100 can
display a new first section containing images of the album within the new
gallery display 3300, in step 3220. For example, the gallery 3300 may
present a new view for images, as shown in FIG. 33. This new view
contains a first section 3308 containing images that are associated with
the selected album. For example, image 3312 and 3316 may be included as
part of the album "Madagascar" 3332 represented or indicated by banner
3320.

[0279] Upon selection of the album 3332, a first image 3336 or an image
contained within the album may be shown in the second section 3324 of the
display. For example, image 3336 is an image contained within the album
Madagascar 3332 and is shown as selected by the visual indicia
surrounding thumbnail 3332. The first section 3308 may be displayed on a
first screen 110 while the second section 3324 is displayed on a portion
of the first screen 110 and the second screen 114. The first section 3308
may be navigable as described in conjunction with FIGS. 29 through 31. As
there may be more images within the album than can be displayed in the
first section 3308, the first section 3308 may be scrollable or movable
to view other thumbnails within the album.

[0280] The second section 3324 of the album display may display only a
single image. The image displayed in the second section 3324 may be
associated with the thumbnail 3332 in the first section 3308. When the
image thumbnail 3332 in the first section 3308 is selected, the related
image 3336 may be displayed in the second section 3324. Further,
highlighting or a highlighted box or other visual indicia may be included
with the thumbnail 3332 as shown in the first section 3308. For example,
thumbnail 3328 includes a box surrounding the image indicating it has
been selected for display in second section 3324.

[0281] The method 3200 can continue with the reception of a second
selection of a second thumbnail in the first section 3308 of the albums
displayed in the view 3324. The device 100 may receive the selection of
the thumbnail, in step 3224. In response to the received selection of a
thumbnail in section 3308, the device 100 may display a second image
associated with the second thumbnail in the second section 3224, in step
3228.

[0282] The image selected in the album may be a video. A second input may
be received that selects the video from section 3308. The selection may
then display an initial screen for the video in section 3324. Further, in
response to the second input or selection, one or more video controls may
be displayed in the second section 3324. For example, video controls may
be as described in conjunction with FIG. 38.

[0283] Another example of the album display 3300 is shown in FIG. 34. In
this example, the second section 3324 may be kept on a second screen 114
and the first section 3308 may be kept on a first screen 110. Thus, the
image 3326 may not be displayed across the seam 3404 of the device 100.
This way the seam 3404 will not dissect the displayed image 3336 and make
the image harder to view.

[0284] An embodiment of a method 3500 for executing an application is
shown in FIG. 35. While a general order for the steps of the method 3500
is shown in FIG. 35. Generally, the method 3500 starts with a start
operation 3504 and ends with an end operation 3524. The method 3500 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 35. The method 3500 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 3500 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-34.

[0285] In method 3500, a device 100 is provided that has at least the
first screen 110 and second screen 114, as described in conjunction with
FIGS. 1B through FIG. 10. The device 100 may receive a first input to the
device 100 to execute a first application, in step 3508. The first
application may be any application executed by the device 100. The
application may receive a second input, in step 3512. In response to the
second input, the first application may request that a picker service
3600 be executed, in step 3516. The picker service 3600 is a special
feature of the gallery function that allows a user to select images or
videos from the gallery 3000 to be input into the first application. An
example of the picker service 3600 is shown in FIG. 36. The picker
service 3600 can display a gallery 3000 of thumbnails 3604 in at least a
portion of the first screen 110 and at least a portion of the second
screen 114, in step 3520.

[0286] As shown in FIG. 36, the picker service 3600 is indicated by the
banner 3616 which contains the word pick. The gallery in the picker
service 3600 can have a first section 3608 and a second section 3612. In
the second section 3612, the picker service 3600 gallery can display one
or more thumbnails, for example thumbnail 3620 displayed in this section
3612. The section 3612 may be displayed as a grid of one or more
thumbnails associated with one or more images stored and provided in the
gallery 3000. The first section 3608 can display one or more thumbnails
associated with one or more albums. As explained herein before, an album
may be a logical structure that stores one or more images that are
associated together.

[0287] In the picker service 3600, the first section 3608 is displayed on
a first screen 110 and is navigable. As explained herein before, the
first section 3608 may contain one or more album indications 3624, 3628,
however, may not be able to display representations of every album within
the gallery 3000. As such, the user may be able to navigate or scroll
using different user interface inputs to select other albums not shown in
a current view. The second section 3612 of the picker service 3600 may be
displayed over at least a portion of the first screen 110 and at least a
portion of the second screen 114. This second section 3612 may also be
navigable as all images associated with either an album or the gallery
3000 are not displayable within the limits of the display.

[0288] In the picker service 3600, the device 100 may receive a selection
of an album 3624 in the first section 3608. In response to receiving this
selection of an album, one or more thumbnails 3620 associated with the
album 3624may be displayed in the second section 3612. Further, if a
second selection of a second thumbnail 3628 in section 3608, representing
a second album, is received, the device 100 in response to the second
selection, may display at least a second image associated with this
second album 3628. The second section 3612 may display a grid of images
associated with the second album 3628. However, as described in
conjunction with FIGS. 32 through 34, the second section 3612 may display
a single image associated with the album.

[0289] The method 3500 may further allow for the selection of a thumbnail
associated with an image shown in section 3612. The selection of a
thumbnail 3620 is interpreted as the user picking that image associated
with the thumbnail and the image is to be provided to the first
application. As such, in response to the selection of an image, the
device 100 automatically provides the image to the first application. The
first application may then edit, manage, send, or do other functions to
the image provided by the device 100.

[0290] An embodiment of a method 3700 for executing an application is
shown in FIG. 37. While a general order for the steps of the method 3700
is shown in FIG. 37. Generally, the method 3700 starts with a start
operation 3704 and ends with an end operation 3724. The method 3700 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 37. The method 3700 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 3700 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-36.

[0291] In method 3700, a device 100 may be presented with at least a first
screen 110 and the second screen 114, as described in conjunction with
FIGS. 1A through FIG. 10. A first input may be received by the device
100, in step 3708. In response to the first input, the device 100 may
execute a gallery function as described herein before. As the first input
may be to execute a video or to play a video contained in the gallery
3000, the device 100 may execute a video player of the gallery function,
in step 3716. The video player may then display a video across at least a
portion of the first screen 110 and/or second screen 114, in step 3720.
An example of the video player may be as shown in FIG. 38.

[0292] The first input may be received from an application already
executing on the device 100. For example, an application such as a web
browser may receive a selection to play a video. The video player of the
gallery function may then be executed in response to a directive or
indication sent from the application. After the video begins playing, the
video gallery 3000 replaces the application display on the first screen
110 and the second screen 114 with the display of the video. Thus, the
video player can be played across both the first screen 110 and the
second screen 114, and the application, which was previously executing,
is no longer seen. For example, the video player 3804 is playing on top
of an application displayed previously that is currently under the
display of the video player 3804.

[0293] In some instances, a second input may be received by the device 100
that opens another window over the top of the video player, such that the
video player can no longer be seen. However, unlike other applications
which may be suspended, the video player may continue to play the video.
Thus, the video player may continue to provide audio output that can be
heard by the user but the video output cannot be seen, as the second
window is displayed over the top of the video player.

[0294] While a video is being played by the video player, the device 100
may prevent the device from timing out. For example, after a period of
time of inactivity, a device 100 may time out and starts a power saving
mode. In the power saving mode, the screens 110, 114 may be disabled and
display nothing and other functions may be stopped. However, when playing
a video, the video may prevent timeouts where the video may be stopped
without activity. For example, the device 100 may receive a third input
to enter a standby mode. The standby mode may be a mode in which the
device 100 does not display anything but is ready to receive input to
begin executing again. However, with the video playing, the device 100
may continue to play the video even in standby mode. Thus, the device 100
can save power by entering a standby mode but till continue to play the
video.

[0295] The device 100 can be docked and receive a fourth input that
indicates that the device 100 is docked with an external display. The
device 100 may then reroute audio and video from the device 100 to an
external display in response to receiving input that the device 100 has
docked. Further, the audio and video playback may be stopped on the
device 100 if video is played to the external monitor.

[0296] The selection or input to play a video may also be a selection of a
video within a gallery 3000. Thus, as explained previously in conjunction
with FIGS. 22 through 36, the gallery 3000 can display an image
representing a video stored in the gallery 3000. Upon selection of the
thumbnail representing the video, the video player may be executed in the
gallery function and play the video selected.

[0297] An embodiment of a method 3900 for executing an application is
shown in FIG. 39. While a general order for the steps of the method 3900
is shown in FIG. 39. Generally, the method 3900 starts with a start
operation 3904 and ends with an end operation 3932. The method 3900 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 39. The method 3900 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 3900 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-38.

[0298] In method 3900, the device 100 may be provided with a first screen
110 and a second screen 114. Input may be received, by the device 100, to
execute a gallery function, in step 3908. The input may cause the device
100 to execute the gallery function, in step 3912. The input may be a
selection in a gallery of a video to play or some other input to play a
video, as such, the device 100 can execute a video player of the gallery
function, in step 3916.

[0299] The device 100 then displays the video with the video player across
at least a portion of the first screen 110 and/or at least a portion of
the second screen 114, in step 3920. Thereinafter, while playing the
video or while displaying the video player, the device 100 may determine
that a connection has been made to an HDMI output, in step 3924. HDMI may
be any high definition multimedia interface connection. This connection
may be made from the device 100 to an external display either directly or
through a port or docking station. Upon determining that a connection has
been made to an HDMI output, the device 100 may provide a user selectable
icon in the display to allow the user to send the video to the HDMI
output, in step 3928.

[0300] For example, in FIG. 40, the video player 4004 may be displaying a
video 4012. Upon receiving the HDMI connection and determining that the
connection has been made, the device 100 may change the display to
include icon 4008. The user selectable icon 4008 may be chosen by the
user to send the video to the HDMI output. Thus, the device 100 may
receive a selection of the user selectable icon 4008.

[0301] In response to receiving the selection of the user selective icon
4008, the device 100 may send the video to the HDMI output. Upon sending
the video to the HDMI output, the video player may stop the video
playback on the device 100. However, the video player may remain active
on the device 100 and control the display of the video on the external
monitor that is receiving the video through the HDMI output.

[0302] For example, as shown in FIG. 41, video player 4004 remains active
on the device 100 while the video 4112 is playing on an external monitor
4108 through a connection 4116 from the HDMI output of the device 100.
The video player 4004 includes a control bar 4104 that can control the
play of the video 4112 that is being displayed on the external monitor
4108. Thus, the video player 4004 continues to control the playback of
the video 4112 although it is being displayed on an external monitor
4108. The display of the video player 4004, as shown in FIG. 41, provides
a controller screen that allows the control of the video 4112 without
actually displaying the video. The controller screen and more
specifically the controller bar 4104 can still include the icon 4008.

[0303] The controller screen 4004 as shown on FIG. 41 can receive a second
selection of the user selectable icon 4008. In response to receiving the
selection of the icon 4008, the video player 4004 can stop the playback
of the video 4112 over the HDMI output to the external monitor 4108. The
device 100 may then replay the video or begin playing the video again on
the display of the device 100.

[0304] The other controls in the control bar 4104 may execute other
controls on the video as it is displayed on the external monitor 4108.
For example, the device 100 can receive a selection of a zoom button or
other buttons, such as button 4120, in the control screen 4004. The
selection of the zoom button 4120 can change the display of the video
4112 on the external monitor 4108. Thus, beyond just playing and stopping
the video 4112, the video controller 4004 can also change how the video
is displayed on the external monitor 4108.

[0305] The HDMI connection may be disconnected or lost for various
reasons. For example, the user may simply disconnect the device 100 from
the HDMI output to leave or stop displaying the video on the external
monitor 4108. The device 100 can determine that the HDM connection is
lost. Upon determining or in response to the HDM connection being lost,
the video player 4004 can stop the playback of the video over the HDMI
output and replay the video on the device 100. Thus, the user need not
select icon 4008 to begin playing the video on the device 100 but can
simply disconnect the device 100 from the external monitor 4108. This
process provides the user with more mobility and less input if they wish
to leave.

[0306] An embodiment of a method 4200 for executing an application is
shown in FIG. 42. While a general order for the steps of the method 4200
is shown in FIG. 42. Generally, the method 4200 starts with a start
operation 4204 and ends with an end operation 4232. The method 4200 can
include more or fewer steps or can arrange the order of the steps
differently than those shown in FIG. 42. The method 4200 can be executed
as a set of computer-executable instructions executed by a computer
system and encoded or stored on a computer readable medium. Hereinafter,
the method 4200 shall be explained with reference to the systems,
components, modules, software, data structures, user interfaces, etc.
described in conjunction with FIGS. 1-41.

[0307] In method 4200, a device 100 can also be provided that has at least
a first screen 110 and a second screen 114. The device 100 can receive a
first input to the device 100, in step 4208. The first input can be an
input to execute a gallery function. The galley function may be executed
by the device 100, in step 4212. Further, the first input may also be a
directive to display a video with the gallery function. Thus, the device
100 can execute a video player 4004 of the gallery function, in step
4216. The device 100 may then display the video with the video player
4004, in step 4220.

[0308] Thereinafter, the device 100 can receive an input to move the
display of the video between a first screen 110 and second screen 114, as
shown in FIGS. 43 through 44, in step 4224. The input can be a drag of a
finger in the touch sensitive display 110, 114, as described
hereinbefore, a flick in an gesture capture region 120, 124, or some
other user input or gesture that attempts to manage the display screen
shown on the device 100 in FIG. 43. For example, the user may attempt to
move the window 4004 from screen 110 to screen 114. As the display 4004
is moved off of screen 110 and onto screen 114, the window 4404 or
desktop underneath a display 4004 may be displayed, as shown in FIG. 44.
Thus, desktop or window 4404 may become uncovered as the display 4304 is
moved. Further, this window, on the second screen 114, for example,
window 4308, may become obscured while the window 4004 is moving onto the
second screen 114.

[0309] The display of a video on a device 100 is display and processor
intensive. Thus, trying to move a display of a video while the video is
being played becomes more intensive and may be too problematic for the
two screen device 100. Thus, in order to show that the movement of the
display is happening, the device 100 may display an icon or other visual
indicia 4408 on the second screen 114 as the display is being moved. The
device 100 displays the icon 4408 on the second screen 114 to intimate
that the movement of the display 4304 is occurring, in step 4228.

[0310] The icon 4408 can be any kind of visual indicia, however, may
appear to complete the display box or configuration on the second screen
114. During the movement, the device 100 may continue to display the
video in the video window 4004 on the first screen 110. However, only the
icon 4408 may be displayed on the second screen 114. The icon 4408 may
not display video but rather provides some other static visual indicia
that intimate movement of the display 4004. Further, the icon 4408 moves
in conjunction with the second input movement. Thus, as the user drags
their finger the icon 4408 moves in conjunction with the movement of the
input. To the user, it appears that the icon 4408 is controlled by the
input of the user.

[0311] During the movement and the display of the video, the display
screen 4004 appears to move off the first screen 110. Upon the video
being moved completely to the second screen 114 or because the user made
enough of an indication of the movement, the display window 4004 may be
expanded onto the second window 114 where the display of the video is
contained completely on the second screen 114. In other words, the user
need not make a complete movement gesture but enough for the device 100
to understand the movement should be completed.

[0312] The use of the video icon may not occur in some situations while
expanding the video. For example, the device 100 can determine that the
movement is an expansion of the display 4004 to cover both the first
screen 110 the second screen 114 in a full screen mode. Upon determining
that the movement is an expansion, the device 100 can expand the display
4004 across both screens 110 and 114, as shown in FIG. 45. During the
expansion of the video, the video may remain or continue to be displayed
during the expansion. Thus, as this display screen 4004 expands into the
second screen 114, the video may be played on the first screen 110 and a
portion of the second screen 114 until the video is fully expanded, as
shown in FIG. 45. No icon is shown during the expansion of the video
rather the video remains in single window, which displays the video.

[0313] Furthermore, while the exemplary aspects, embodiments, and/or
configurations illustrated herein show the various components of the
system collocated, certain components of the system can be located
remotely, at distant portions of a distributed network, such as a LAN
and/or the Internet, or within a dedicated system. Thus, it should be
appreciated, that the components of the system can be combined in to one
or more devices, such as a tablet-like device, or collocated on a
particular node of a distributed network, such as an analog and/or
digital telecommunications network, a packet-switch network, or a
circuit-switched network. It will be appreciated from the preceding
description, and for reasons of computational efficiency, that the
components of the system can be arranged at any location within a
distributed network of components without affecting the operation of the
system. For example, the various components can be located in a switch
such as a PBX and media server, gateway, in one or more communications
devices, at one or more users' premises, or some combination thereof.
Similarly, one or more functional portions of the system could be
distributed between a telecommunications device(s) and an associated
computing device.

[0314] Furthermore, it should be appreciated that the various links
connecting the elements can be wired or wireless links, or any
combination thereof, or any other known or later developed element(s)
that is capable of supplying and/or communicating data to and from the
connected elements. These wired or wireless links can also be secure
links and may be capable of communicating encrypted information.
Transmission media used as links, for example, can be any suitable
carrier for electrical signals, including coaxial cables, copper wire and
fiber optics, and may take the form of acoustic or light waves, such as
those generated during radio-wave and infra-red data communications.

[0315] Also, while the flowcharts have been discussed and illustrated in
relation to a particular sequence of events, it should be appreciated
that changes, additions, and omissions to this sequence can occur without
materially affecting the operation of the disclosed embodiments,
configuration, and aspects.

[0316] In yet another embodiment, the systems and methods of this
disclosure can be implemented in conjunction with a special purpose
computer, a programmed microprocessor or microcontroller and peripheral
integrated circuit element(s), an ASIC or other integrated circuit, a
digital signal processor, a hard-wired electronic or logic circuit such
as discrete element circuit, a programmable logic device or gate array
such as PLD, PLA, FPGA, PAL, special purpose computer, any comparable
means, or the like. In general, any device(s) or means capable of
implementing the methodology illustrated herein can be used to implement
the various aspects of this disclosure. Exemplary hardware that can be
used for the disclosed embodiments, configurations and aspects includes
computers, handheld devices, telephones (e.g., cellular, Internet
enabled, digital, analog, hybrids, and others), and other hardware known
in the art. Some of these devices include processors (e.g., a single or
multiple microprocessors), memory, nonvolatile storage, input devices,
and output devices. Furthermore, alternative software implementations
including, but not limited to, distributed processing or component/object
distributed processing, parallel processing, or virtual machine
processing can also be constructed to implement the methods described
herein.

[0317] In yet another embodiment, the disclosed methods may be readily
implemented in conjunction with software using object or object-oriented
software development environments that provide portable source code that
can be used on a variety of computer or workstation platforms.
Alternatively, the disclosed system may be implemented partially or fully
in hardware using standard logic circuits or VLSI design. Whether
software or hardware is used to implement the systems in accordance with
this disclosure is dependent on the speed and/or efficiency requirements
of the system, the particular function, and the particular software or
hardware systems or microprocessor or microcomputer systems being
utilized.

[0318] In yet another embodiment, the disclosed methods may be partially
implemented in software that can be stored on a storage medium, executed
on programmed general-purpose computer with the cooperation of a
controller and memory, a special purpose computer, a microprocessor, or
the like. In these instances, the systems and methods of this disclosure
can be implemented as program embedded on personal computer such as an
applet, JAVA® or CGI script, as a resource residing on a server or
computer workstation, as a routine embedded in a dedicated measurement
system, system component, or the like. The system can also be implemented
by physically incorporating the system and/or method into a software
and/or hardware system.

[0319] Although the present disclosure describes components and functions
implemented in the aspects, embodiments, and/or configurations with
reference to particular standards and protocols, the aspects,
embodiments, and/or configurations are not limited to such standards and
protocols. Other similar standards and protocols not mentioned herein are
in existence and are considered to be included in the present disclosure.
Moreover, the standards and protocols mentioned herein and other similar
standards and protocols not mentioned herein are periodically superseded
by faster or more effective equivalents having essentially the same
functions. Such replacement standards and protocols having the same
functions are considered equivalents included in the present disclosure.

[0320] The present disclosure, in various aspects, embodiments, and/or
configurations, includes components, methods, processes, systems and/or
apparatus substantially as depicted and described herein, including
various aspects, embodiments, configurations embodiments,
subcombinations, and/or subsets thereof. Those of skill in the art will
understand how to make and use the disclosed aspects, embodiments, and/or
configurations after understanding the present disclosure. The present
disclosure, in various aspects, embodiments, and/or configurations,
includes providing devices and processes in the absence of items not
depicted and/or described herein or in various aspects, embodiments,
and/or configurations hereof, including in the absence of such items as
may have been used in previous devices or processes, e.g., for improving
performance, achieving ease and\or reducing cost of implementation.

[0321] The foregoing discussion has been presented for purposes of
illustration and description. The foregoing is not intended to limit the
disclosure to the form or forms disclosed herein. In the foregoing
Detailed Description for example, various features of the disclosure are
grouped together in one or more aspects, embodiments, and/or
configurations for the purpose of streamlining the disclosure. The
features of the aspects, embodiments, and/or configurations of the
disclosure may be combined in alternate aspects, embodiments, and/or
configurations other than those discussed above. This method of
disclosure is not to be interpreted as reflecting an intention that the
claims require more features than are expressly recited in each claim.
Rather, as the following claims reflect, inventive aspects lie in less
than all features of a single foregoing disclosed aspect, embodiment,
and/or configuration. Thus, the following claims are hereby incorporated
into this Detailed Description, with each claim standing on its own as a
separate preferred embodiment of the disclosure.

[0322] Moreover, though the description has included description of one or
more aspects, embodiments, and/or configurations and certain variations
and modifications, other variations, combinations, and modifications are
